"Sonic Generations: White Space-time"}} is a platformer video game developed by [[Sonic Team]] and published by [[Sega]] in late 2011, to celebrate the [[Sonic the Hedgehog 20th Anniversary|20th anniversary]] of the [[Sonic the Hedgehog series|''Sonic the Hedgehog'' series]]. The game was released for the [[Xbox 360]] and [[PlayStation 3]] consoles, alongside a [[PC]] port by British developer Devil's Details; an [[Sonic Generations (Nintendo 3DS)|alternate version]] of the game was also co-developed by Sonic Team and [[Dimps]] for the [[Nintendo 3DS]].

''Generations''{{'}} gameplay is divided into two styles: "Classic", which plays from a side-scrolling perspective akin to the [[Sega Mega Drive]] platformers, and "Modern", which combines 2D and 3D gameplay and follows a formula similar to that of ''[[Sonic Unleashed]]'' (2008) and ''[[Sonic Colors]]'' (2010). In the game's story, [[Sonic the Hedgehog|Sonic]] celebrates his [[Sonic's birthday|birthday party]] with his friends, only for them to be kidnapped by the [[Time Eater]] and left trapped in [[White Space]]. Teaming up with a younger version of himself, Sonic explores White Space to find his friends, defeat the Time Eater and return home. The game received positive reviews, gathering praise for its visuals, gameplay, and audio, but criticism for its story and occasional frame rate and control problems. It is considered one of the best games in the franchise, as well as a good tribute to the series' history.

All versions of this game can be played in [[Wikipedia:Stereoscopic video game|stereoscopic 3D]], but a 3DTV as well as a pair of 3D glasses are required for the PlayStation 3 and Xbox 360 versions, being the first game of the franchise to support stereoscopic 3D. The PlayStation 3 version was available to be streamed on the [[PlayStation 4]], [[PlayStation 5]], and [[PC]] via the PS Now subscription service, with PlayStation 3, [[PlayStation Vita]], Sony Bravia Smart TV (2013, 2014, 2015 and 2016 models), Sony Blu-Ray players and Samsung Smart TV support for the service being dropped in 2017. In April 2018, the [[Xbox 360]] version of the game was made backwards compatible with the [[Xbox One]] and supports Xbox One X enhanced features, as well as FPS Boost for the [[Xbox Series X and Series S]] since 15 November 2021, making the game run at 60fps.<ref name="XOneEnhanced">{{Cite web|url=https://news.xbox.com/en-us/2018/04/10/backward-compatibility-april-update/|title=More Original Xbox Games Coming to Xbox One Backward Compatibility|last=Stillwell|first=Bill|work=[[Microsoft]]|date=10 April 2018|accessdate=23 April 2018}}</ref>

In January 2024, it was announced that ''Generations'' would be remastered in a bundle called ''[[Sonic X Shadow Generations]]'', alongside a new title called ''[[Shadow Generations]]'', which stars [[Shadow the Hedgehog|Shadow]]. The game was released in October 2024. As a result, the original game was delisted for every platform on 9 September 2024.<ref>{{Cite web |url=https://x.com/sonic_hedgehog/status/1821939586194665575?t=INpP4eDcGlQLgSSPwJblqg&s=19 |work=Twitter |title=Sonic the Hedgehog on Twitter |date=9 August 2024 |accessdate=9 August 2024 |quote=We're excited to share SONIC X SHADOW GENERATIONS with you this October and see a new generation cherish this game as much as we do!

==Plot==
{{Spoiler}}
[[File:Sonic Generations Title Screen.png|thumb|left|225px|The title screen of ''Sonic Generations'', featuring an emblem with Classic Sonic on the left and Modern Sonic on the right.]]
The game opens with the distant past; [[Sonic the Hedgehog|Classic Sonic]] is running through [[Green Hill]] until a mysterious entity known as the [[Time Eater]] appears in the sky, causing everything to white out.

In the present day, [[Sonic the Hedgehog|Modern Sonic]] celebrates [[Sonic's birthday|his birthday]] with his friends. However, the Time Eater disrupts the party by sucking everyone through various [[Time Hole]]s. Modern Sonic attempts to attack but is knocked down. He wakes up in a strange dimension known as [[White Space]], finding a colorless Green Hill and a statue-like [[Miles "Tails" Prower|Tails]]. By running through Green Hill, Modern Sonic restores its color and Tails to normal. They then notice the [[Chemical Plant]] in the same colorless state and Sonic heads there. Classic Sonic, mistaken for his Modern version by Tails, also heads there. After restoring the area, the Sonics unknowingly work together to restore various zones and rescue their friends. Classic Sonic defeats [[Metal Sonic]] in [[Stardust Speedway]] and claims a [[Chaos Emerald]] from him. Later, the Sonics meet inside a [[Boss Gate]], separated by a glass wall. Classic Sonic defeats [[Doctor Eggman|Classic Eggman]] and his [[Death Egg Robot]]. The Sonics and their respective Tails counterparts then meet in White Space, deducing that they are traveling through time and space and must stop the Time Eater.

The Sonics restore various locations, restoring their friends in the process. Modern Sonic claims Chaos Emeralds after defeating [[Shadow the Hedgehog|Shadow]] and [[Perfect Chaos]], and later [[Silver the Hedgehog|Silver]] and Modern Eggman in the [[Egg Dragoon]]. Meanwhile, the two Tails figure out that the Time Eater is tearing space apart as it moves through time, ripping places from across spacetime and leaving them colorless in White Space, but the Sonics are able to restore them by speeding through time. Along the way, the heroes also learn of the Time Eater's sensitivity to the Chaos Emeralds.

[[File:Timeeater.png|thumb|225px|The heroes face the [[Time Eater]].]]
After collecting all the Chaos Emeralds, the Classic and Modern pairs confront the Time Eater in its domain, where the Eggmen reveal that they are the ones piloting the creature. Modern Eggman explains that he found the primordial form of the Time Eater while stranded in space<ref group="note">As depicted in the ending of ''[[Sonic Colors]]'' (2010)</ref> and decided to use its powers to undo his previous defeats. Through the support of their friends, the Sonics use the Chaos Emeralds to transform into [[Super Sonic]]s and destroy the Time Eater, restoring the timeline.

The heroes then return to the present time and continue celebrating Modern Sonic's birthday. Modern Sonic thanks his Classic counterpart for the team-up and bids farewells to him and Classic Tails when a Time Hole appears for them to return home. Meanwhile, the Eggmen are stranded in White Space where they argue about their failures.

==Gameplay==
''Sonic Generations'' is a platforming video game, with bits of gameplay taken from past ''[[Sonic the Hedgehog series|Sonic]]'' games. The player takes control of either [[Sonic the Hedgehog/History and appearances (1991 - 2006)|Classic Sonic]] or [[Sonic the Hedgehog|Modern Sonic]], each with their own abilities and levels.

''Sonic Generations'' is divided into nine [[zone|stages]], all of which are taken from past ''Sonic'' games, which are composed on two Acts, the first one with the player controlling Classic Sonic, and the second one having them playing as Modern Sonic. The goal of ''Sonic Generations'' is to beat the aforementioned Acts in the least amount of time as possible. These Acts are designed to make use of each character's abilities and branch into multiple paths that can offer the player more secrets to find. In addition, the player will unlock boss stages and [[Challenge Act]]s as they progress with the game, both of which have to be completed in order to progress with the story, although most Challenge Acts are optional.

During gameplay, the player will encounter obstacles and enemies. Also common are the [[Ring]]s, which serve as the playable character's health. The number of Rings carried by the player is displayed in the top left corner of the HUD. As with past ''Sonic'' games, Rings serve as the playable character's main method of protection from damage; if the playable character takes damage while they carry at least one Ring, they will survive, though they will lose all their Rings. Conversely, taking damage while not holding any Rings will cost the player a [[life]]. The player will also lose a life if they drown underwater, get [[crusher|crushed]], or fall into a [[bottomless pit]]. After losing a life, the playable character will respawn at the latest [[Star Post]] they touched, or at the start of an Act if they have not touched any Star Post. If the player runs out of lives, they will get a [[Game Over]]. Extra lives can be obtained by collecting [[1-Up]]s or by gathering 100 Rings.

''Sonic Generations'' also includes [[Skill]]s, which are optional booster items the player can buy to get an advantage in levels or get exclusive content. This can be done through the [[Skill Shop]], which allows players to use points earned from high scores to unlock upgrades such as abilities, shields, and even the original ''[[Sonic the Hedgehog (1991)|Sonic the Hedgehog]]'' video game (console version). Completing challenges, as well as finding Red Star Rings hidden in each of the main Acts, unlocks additional Skills, as well as bonus concept artwork and music.

===Character specific gameplays===
====Classic Sonic====
[[File:Sky Sanctuary 6.png|thumb|225px|[[Sonic the Hedgehog|Classic Sonic]] in [[Sky Sanctuary (Sonic Generations)|Sky Sanctuary]], the third [[zone|stage]] in the game.]]
[[Sonic the Hedgehog/History and appearances (1991 - 2006)|Classic Sonic]] has a 2.5D side-scroller gameplay, the same as that from the 2D [[Sega Mega Drive]] ''Sonic'' games, though with some modifications to be more adapted to the newer level design. As with the aforementioned games, Classic Sonic can run, [[Spin Jump|jump]], and [[Spin Attack|roll]] as his most basic abilities. In addition, he can also [[Spin Dash]] while standing still to be launched at incredible speeds. Classic Sonic's Acts end when he touches a [[Goal Post]] at the end of the stage.

====Modern Sonic====
[[File:Sonic Generations Seaside Hill (1).jpg|thumb|left|225px|[[Sonic the Hedgehog|Modern Sonic]] in [[Seaside Hill (Sonic Generations)|Seaside Hill]], the sixth [[zone|stage]] in the game.]]
[[Sonic the Hedgehog|Modern Sonic]]'s gameplay resembles that of ''[[Sonic Unleashed]]'' and the [[Wii]] version of ''[[Sonic Colors]]''. Occasionally, the camera will shift between a side-view angle and a third-person angle, offering a 2.5D side-scroller gameplay and a 3D gameplay respectively. Like Classic Sonic, he can run and jump, those being his most standard abilities. However, he can also [[Boost]] to run at incredibly high speeds and destroy almost everything that is in his way, though this ability is limited and cannot be performed if the player's [[Boost Gauge]] is empty. Sonic can also perform a [[Homing Attack]] to reach nearby targets with ease, and [[slide]] to pass through small spaces with ease. Modern Sonic's Acts end when he touches a [[Goal Ring]].

In addition to the main stages, [[Casino Night (Sonic Generations) (console/PC)|Casino Night]] from ''Sonic the Hedgehog 2'' is also included as an optional stage in the Classic Era as [[Downloadable content|DLC]].

==Bosses==
''Generations''{{'}} bosses are divided in two: "rival" bosses and major bosses. Each era has a rival and a major boss. Both types are based on individual bosses from previous games and are fought in the location they were originally encountered. Defeating each boss grants the player a [[Chaos Emerald]], which is needed to beat the game. A final boss, the Time Eater, is fought after the seven Emeralds are obtained.

==Other modes==
===30-second Trial===
[[File:Sonic Generations 30 second trial.png|thumb|225px|30-second Trial gameplay.]]
In '''30-second Trial''' mode, the player has to get as far as they can in a stage in thirty seconds. After time runs out, a sign post is placed in the spot where the player is standing. However, if they reach the goal before the time runs out (which is only possible through hacks), the mode abruptly ends without the score saved. They have the option to try again or continue playing to find the sign posts of their friends. They can also upload their score online and see which of their friends made it the farthest in one specific level.

===Time Attack===
{{Main|Time Attack}}
In '''Time Attack''' mode, the player can see how fast they can clear a stage, a rival, or a boss fight, and can share their time in online leader-boards. In the console version, Time Attack can only be done online, and only the eighteen main Acts can be played for a top time.

==Collections==
===Unlockable music===
Music can be unlocked by completing some [[Challenge Act]]s or collecting a number of [[Red Star Ring]]s. The player can view the unlocked music by going to the collection room. The music for each stage in the game can be replaced by any unlocked music.

There are a total of fifty unlockable tracks:

==Development==
Development of ''Sonic Generations'' began shortly after the release of ''[[Sonic Unleashed]]'', when [[Sonic Team]] began discussing ideas for a 20th anniversary ''Sonic'' game, with producer [[Takashi Iizuka]] wanting a game that incorporated the best of the series' history. The team eventually chose to split the gameplay into two playstyles: one based on the original games and another on the more recent ones.<ref name="THoStH">{{Cite book |date=6 September 2013 |title=[[The History of Sonic the Hedgehog]] |publisher=Les Editions Pix'n Love |pages=107-109 |chapter=History |isbn=978-1-926778-96-9}}</ref><ref name="StadiumQ&A">{{Cite web |first=Jason |last=Berry |date=14 June 2011 |title=E3 2011 Q&A: Takashi Iizuka on Sonic Generations |url=https://www.sonicstadium.org/2011/06/e3-sonic-generations-qa-with-takashi-iizuka/ |publisher=Sonic Stadium |archivedate=2 April 2021 |archiveurl=https://web.archive.org/web/20210402140416/https://www.sonicstadium.org/2011/06/e3-sonic-generations-qa-with-takashi-iizuka/ |accessdate=5 February 2024}}</ref><ref name="Inside">{{Cite web |date=26 September 2011 |title=【TGS 2011】20周年でしか出来ないチャレンジを・・・『ソニック ジェネレーションズ』飯塚氏インタビュー | インサイド |url=https://www.inside-games.jp/article/2011/09/26/51767.html |language=Japanese |work=Inside Games |accessdate=5 February 2024}}</ref> Sonic Team chose to develop the game on the [[Xbox 360]] and [[PlayStation 3]] consoles, wanting the game to reimagine levels from previous installments with high-quality graphics.<ref name="NintendoPower">{{Cite journal |first1=Steve |last1=Thomason |title=Nintendo Power |url=https://archive.org/details/nintendo-power-collection/Nintendo%20Power%20Issue%20268%20%28June%202011%29/page/40 |issue=268 |page=40-47 |accessdate=5 February 2024}}</ref> A port for [[Personal computer|PC]] was handled by the British developer Devil's Details.

While ''[[Sonic Colors]]'' was made for a more casual-oriented audience, ''Sonic Generations'' was made to appeal to the series' core fans.<ref name="IGNCons" /> The script was written by ''Colors''{{'}} writers [[Ken Pontac]] and [[Warren Graff]]; according to Pontac, they had more imput on the story than in ''Colors''.<ref name="Pontaff">{{Cite web |first=Danica |last=Davidson |date=25 November 2013 |title=Ken Pontac Talks Game Writing and Anime |url=http://www.otakuusamagazine.com/Games/News1/Ken-Pontac-Talks-Game-Writing-and-Anime-5382.aspx |work=Otaku USA Magazine |quote=On the Sonic games, ''Generations'' and ''Colors'', Warren and I [Pontac] were pretty much given the story and cutscenes. In ''Colors'', we were given what each cutscene should be, because the story progressed that much before we were called in. We were to write the dialogue. In ''Generations'', we had more input on the story and wrote the dialogue and descriptions for the cutscenes as well. In ''Lost World'', we got to come up with the story and write the cutscenes. |archivedate=9 May 2014 |archiveurl=https://archive.ph/20140509203120/http://www.otakuusamagazine.com/Games/News1/Ken-Pontac-Talks-Game-Writing-and-Anime-5382.aspx |accessdate=5 February 2024}}</ref> ''Generations'' makes use of the [[Hedgehog Engine]], the engine previously used for ''Unleashed''. To decide which levels would appear in the game, Sega polled their employees and conducted an Internet survey about popular ''Sonic'' stages, with the ones that were found most popular being incorporated into the game.<ref name="NintendoPower" /><ref name="THoStH" /> Sonic Team decided not to reuse older assets or level designs, and certain stages were given new visual elements for more dynamic. Additionally, the developers only chose stages with different concepts and gameplay styles, with [[Emerald Hill Zone]] from ''[[Sonic the Hedgehog 2]]'' not being put into the game due to its similarities to [[Green Hill Zone (Sonic the Hedgehog)|Green Hill Zone]] despite its popularity.<ref name="THoStH" /> Recreating the "classic" ''Sonic'' gameplay was cited as challenging, since the Hedgehog Engine was made for 3D gameplay. The developers chose to make the [[Spin Dash]] quicker to use to help younger players who may be unfamiliar with it.<ref>{{Cite web |first=Jason |last=Berry |date=28 July 2011 |title=Interview: Aaron Webber |url=https://www.sonicstadium.org/2011/07/interview-with-aaron-webber/ |publisher=Sonic Stadium |archivedate=13 March 2021 |archiveurl=https://web.archive.org/web/20210313233407/https://www.sonicstadium.org/2011/07/interview-with-aaron-webber/ |accessdate=5 February 2024}}</ref>

==Promotional==
In late 2010, rumors of a ''Sonic Anniversary'' game surfaced online.<ref>{{Cite web|url=https://archive.sonicstadium.org/2010/10/new-mario-and-sonic-sonic-20th-anniversary-game-confirmed/|title=New Mario and Sonic, Sonic 20th Anniversary Game Rumored|author=Nuckles87|date=10 October 2010|work=The Sonic Stadium}}</ref> The rumors told of a game that would potentially feature remakes of levels from throughout the series' history in both 2D and 3D. The game was alleged to be released on all major game consoles at the time: [[PlayStation Portable]], [[PlayStation 3]], [[Xbox 360]], [[Wii]], and [[Nintendo DS]].

On 18 April 2011, ''Sonic Generations'' was finally announced for the PlayStation 3 and Xbox 360. A GameStop release list printed on 7 May 2011 showed a [[Nintendo 3DS]] port of ''Generations'' with a tentative release date of 31 December 2011. Later in the month, a Sega-Sammy earnings report listed Nintendo 3DS and [[PC]] versions of the game; however, a revised version of the report no longer listed either version.<ref>{{Cite web|url=https://archive.sonicstadium.org/2011/05/sonic-generations-3ds-pc-listings-removed-cream-the-rabbit-teased/|title=Sonic Generations 3DS & PC Listings Removed, Cream the Rabbit Teased|author=Shadzter|date=20 May 2011|work=The Sonic Stadium}}</ref> The June 2011 issue of [[Nintendo Power]] finally confirmed a 3DS version of ''Sonic Generations''.<ref>{{Cite web|url=https://archive.sonicstadium.org/2011/05/nintendo-power-confirms-sonic-generations-for-nintendo-3ds/|title=Nintendo Power Confirms Sonic Generations For Nintendo 3DS|author=Shadzter|date=24 May 2011|work=The Sonic Stadium}}</ref> It contained an in-depth preview and interview with Takashi Iizuka.

Sega officially announced a PC version of the game on 11 October 2011.<ref>{{cite web|url=http://blogs.sega.com/2011/10/11/sonic-generations-confirmed-for-pc-digital-download|title=Sonic Generations Confirmed for PC Digital Download|work=[[Sega|Sega Blog]]|date=11 October 2011|author=Kellie|archiveurl=https://web.archive.org/web/20170711151914/http://blogs.sega.com/2011/10/11/sonic-generations-confirmed-for-pc-digital-download/|archivedate=11 July 2017}}</ref> This version was outsourced and developed by the British company Devil's Details.

===Sonic Boom===
{{Main|Sonic Boom (event)}}
[[File:Sonic Boom 2011.jpg|right|180px|The Sonic Boom logo.]]
A ''Sonic Generations'' demo was playable at [[wikipedia:E3 2011|E3 2011]], under the name "Sonic Boom". It was the first major American ''Sonic'' event, being hosted by [[Sega]], and took place on 8 June 2011 at 6pm PST. At E3, ''Sonic Generations'' was playable in both the HD and Nintendo 3DS versions. Although only [[Green Hill (Sonic Generations)|Green Hill]] was playable for the console versions, [[City Escape (Sonic Generations)|City Escape]] was shown. There was also a Birthday Song for Sonic sung at Sonic Boom and the ending of the song, "Happy Birthday Sonic!" was heard in ''Sonic Generations''.<ref>{{Cite web|title=Happy 20th Birthday Sonic|url=https://www.youtube.com/watch?v=fIr-DO8xfvM&t=69|work=YouTube}}</ref> This song appeared at the Tokyo [[wikipedia:Joypolis|Joypolis]] event and at the [[Summer of Sonic]] event in London. It appeared at the Gamescom 2011 event in Germany, and at Tokyo Game Show 2011.

===Demo===
The Australian government’s OFLC rated a multi-platform demo release of ''Sonic Generations'' and [[Sega]] formally announced at E3 that they would release a demo for [[PlayStation 3|PlayStation Network]] and [[Xbox 360|Xbox Live]] on ''Sonic''{{'}}s 20th anniversary, 23 June 2011. The demo only contained [[Green Hill (Sonic Generations)|Green Hill]], and only the [[Sonic the Hedgehog/History and appearances (1991 - 2006)|Classic Sonic]] playthrough. However, this demo also contained many unused files that revealed much about the full game, notably the stage list. The demo was only available until 12 July, at which point it was no longer available, including for players who had already downloaded it; the file essentially locked itself. In the Xbox Live version, one has to be an Xbox Live Gold Member to download the demo, although in the PlayStation Network version, a PlayStation Plus Subscription is not required. The name of the demo was: "''Sonic Generations [[Green Hill (Sonic Generations)|Green Hill Zone]] Demo #1''", indicating another demo was on the way. Sega confirmed on their blog a second demo released in Europe for PlayStation Network and Xbox Live on October 18 and was released in North America for PlayStation Network on 25 October.<ref>{{cite web|url=http://blogs.sega.com/2011/10/17/second-sonic-generations-demo-incoming/|title=Second Sonic Generations Demo Incoming!|work=[[Sega|Sega Blog]]|date=17 October 2011|author=Clumsyorchid|archiveurl=https://web.archive.org/web/20120120114131/http://blogs.sega.com/2011/10/17/second-sonic-generations-demo-incoming/|archivedate=20 January 2012}}</ref> The demo contains both Classic and Modern Sonic playable in Green Hill and has no time limit.

==Cast==
[[Sonic the Hedgehog/History and appearances (1991 - 2006)|Classic Sonic]] is mostly silent throughout the game, showing his personality through his actions and gestures.

For the first time, voice overs exist not only in English and Japanese, but also German, French, Italian and Spanish. The French voice cast (except for Vector) and the German voice cast (except for Shadow, Cream, Vector, Espio, Charmy and Rouge) all reprise their roles from the ''[[Sonic X]]'' anime series. The Spanish voice of Sonic reprised his role from the ''[[Sonic Underground]]'' television series.

Jack Fletcher was the voice director for the English dub, Eriko Kimura and Keiichiro Miyoshi were the voice directors for the Japanese dub, Antoine Nouel returned as the French voice director from ''Sonic X'', Emanuela Ghignoni was the voice director for the Italian dub, Michael Hülsmann was the voice director for the German dub, and Guillermo Reinlein was the voice director for the Spanish dub.

==Soundtrack==
[[File:SGBlueBlur.jpg|thumb|The cover of ''[[Blue Blur: Sonic Generations Original Soundtrack]]''.]]
The soundtrack for ''Sonic Generations'' is called ''"[[Blue Blur: Sonic Generations Original Soundtrack]]''" which includes the Soundtrack for both the console/PC and [[Nintendo 3DS]] [[Sonic Generations (Nintendo 3DS)|versions]] of the game.<ref>{{Cite web|title=SONIC GENERATIONS Original Soundtrack: Blue Blur|url=http://www.amazon.co.jp/SONIC-GENERATIONS-Original-Soundtrack-Blue/dp/B0063HP5UE/ref=sr_1_1?s=music&ie=UTF8&qid=1321043998&sr=1-1|work=Amazon}}</ref><ref>{{Cite web|url=http://www.yesasia.com/global/sonic-generations-original-soundtrack-japan-version/1025686021-0-0-0-en/info.html|title=SONIC GENERATIONS Original Soundtrack:Blue Blur (Japan Version)|publisher=YESASIA}}</ref>

==Adaptations==
[[Archie Comics]] made a video game tie-in for ''Sonic Generations'' in [[Archie Sonic the Hedgehog Issue 230|''Sonic the Hedgehog'' #230]], taking place within the [[In Another Time, In Another Place]] reality. It has also been stated that the events of the game happen in the [[post-Super Genesis Wave timeline]], and led up to ''[[Sonic & Mega Man: Worlds Collide]]''.

A [[Sonic Generations (manga)|short manga]] for ''Sonic Generations'' was released in Japan. It is presented in a similar format as the ''[[Sonic World Adventure (manga)|Sonic World Adventure]]'' manga and the ''[[Sonic Colors (manga)|Sonic Colors]]'' manga.


==Other homages to the series==

*When left waiting long enough without getting talked to in front of [[Green Hill (Sonic Generations)|Green Hill]], [[Miles "Tails" Prower|Modern]] and [[Miles "Tails" Prower/History and appearances (1992 - 2006)|Classic Tails]] yawn like they first did in this game.
*Two of [[Sonic the Hedgehog/History and appearances (1991 - 2006)|Classic Sonic]]'s idle animations, one where he looks at a "watch" on his arm, and one where he impatiently lies back, come from this game.

;''Sonic the Hedgehog CD'':
*[[Sonic the Hedgehog/History and appearances (1991 - 2006)|Classic Sonic]]'s [[Crisis City (Sonic Generations)|Crisis City]] has a 90-degree angle ramp like the "3D" upward ramps in [[Palmtree Panic]]'s present.
**Classic Sonic's [[City Escape (Sonic Generations)|City Escape]] also has a similar ramp.

*On certain challenges, Classic Sonic has to "juggle" the Goal Post to a certain area in the stage.

*One of Classic Sonic's idle animations, where he points ahead of the stage, comes from this game. 
**When facing backwards, this idle animation changes to have Classic Sonic point behind him, instead of reusing the same animation as in the original.

;''Sonic the Hedgehog Triple Trouble'':
*The skateboard item [[Sonic the Hedgehog/History and appearances (1991 - 2006)|Classic Sonic]] uses in [[City Escape (Sonic Generations)|City Escape]] and the skill "Boardmaster" seems very similar to the board in [[Robotnik Winter Zone]].

;''Sonic 3D Blast'':
*One of Classic Sonic's idle animations, where he crosses his arms and quickly taps his foot, is based on Sonic's idle animation from this game.

;''Sonic Adventure'':

;''Sonic Advance 3'':
*In the Amy Co-op Mission in Chemical Plant, she uses her hammer to send up Sonic in the air. This was her partner ability in ''Sonic Advance 3''.
*Sonic is able to call his friends to help him out with their special abilities in some of the missions. He was able to call them in ''Sonic Advance 3'' as well.
*In the final battle, Sonic is able to throw his partner as a projectile to the Time Eater. This feature comes from the final battle of ''Sonic Advance 3''.
*The Spinning Tops in Sky Sanctuary Zone are references to the Spinning Tops in [[Chaos Angel]] (in terms of design, not functionality).

;''Sonic Heroes'':
*In a mission in which Classic Sonic races Amy in Sky Sanctuary, Amy Races by twirling her hammer around in her hands. This seems to reference her [[Propeller Hammer]] move from this game.
*The settings music is remixed from the character select screen theme of this game.

;''Sonic Rush'':
*The Freestyle Tricks Modern Sonic can perform are similar to the ones from this game. They give him boost energy, just like in ''Sonic Rush''.
*Blaze is seen talking to Cream in Sonic's party, a reference to their friendship from this game.
*In the final battle, the Sonics combine their powers and start rotating in a circle to deliver the final blow. This is how the final battle of this game ended.
*Each Sonic having their own remix of the stage theme is just like how Blaze and Sonic both had their own remix of each stages theme in this game.

;''Sonic Rush Adventure'':
*Blaze mentions that there are rings similar to [[Special Rings|Red Rings]] in [[Sol Dimension|her dimension]].
*The dolphins who help Modern Sonic in Emerald Coast are similar to the ones from [[Pirates' Island]].

*The skill system is similar to the ring system from this game.
* The [[Time Break]] ability in ''Sonic Generations'' is very similar to the Time Break in this game, where it originated from.

;''Sonic Chronicles: The Dark Brotherhood'': 
*If the player saves [[Rouge the Bat]] in [[City Escape (Sonic Generations)|City Escape]] as Modern Sonic, she will refer to him as "Big Blue," which was her nickname for Sonic in ''Sonic Chronicles: The Dark Brotherhood''.

*If the player gets a "B"-Rank with Modern Sonic, he will do one of the poses of his artwork from this game.

*If the player gets an "A"-Rank with Modern Sonic, he will do one of the many poses that he has in Sonic Channel.
*Most of the statues are based off the character artwork from here.

==Trivia==
*This is the third 3D mainline ''[[Sonic the Hedgehog series|Sonic]]'' game to utilize the [[Boost|Boost formula]], following ''[[Sonic Unleashed|Sonic]] [[Sonic Unleashed (Wii/PlayStation 2)|Unleashed]]'' and ''[[Sonic Colors]]''.
*No explanation has been given for how both Eggmen managed to escape the white void and return to their respective times at the very end of the game. Ian Flynn wanted to add an explanation for how they escaped in the ''Sonic X Shadow Generations'' remaster, but Takashi Iizuka rejected the idea of expanding on the main story campaign and insisted on leaving it up to the players imagination as to how both doctors escaped instead.<ref>https://www.sonicstadium.org/news/features/interviews/takashi-iizuka-on-sonic-teams-expansion-and-shadows-evolving-motivations-tss-interview-r2254/</ref>
*The internet poll asking fans what their favorite stages from each mainline ''Sonic'' game were also listed stages from ''[[Sonic and the Secret Rings]]'' and ''[[Sonic and the Black Knight]]'', suggesting that at one point in development, stages from both games were meant to appear in ''Sonic Generations'' but were scrapped later on.
**Because ''[[Sonic Colors]]'' was unannounced yet at the time the poll was released, none of its stages appeared in the poll.
*There are some differences between the console and the [[PC]] version of ''Sonic Generations''. First of all, the PC version has more shadows and the colors are extremely less vibrant than on the console version. The maximum framerate for the PC is 60 FPS while it is locked to 30 FPS on consoles (without FPS Boost enabled for the Xbox 360 version). The loading times are also greatly decreased in the PC version, as well as the Xbox 360 version running on Xbox One and [[Xbox Series X and Series S]], and it lacks the [[Sega Genesis Controller]]. 
**However, the Sega Mega Drive version of ''[[Sonic the Hedgehog (1991)|Sonic the Hedgehog]]'' runs at 60 FPS in the console version (even with FPS Boost enabled for the Xbox 360 version).
**Also, in the PC version and the Xbox 360 version via FPS Boost, all cutscenes, including boss intro cutscenes and boss outro cutscenes as well as the Saving A Friend cutscenes, are interpolated at 30 FPS.
**In the PS3 version, Motion Blur is disabled.
*The textures for Planet Wisp's environment map are actually screenshots of the team's dev program.
*All Challenges against friends in the first era are races.
**Tails is the only character who races against the current Sonic. Knuckles and Amy race against [[Sonic the Hedgehog|Classic Sonic]]. This may be seem as a reference to the fact that Tails' levels in ''[[Sonic Adventure]]'' were based in racing against Sonic.
*This is the first 3D ''Sonic'' game not to have a unique theme song. 
**As such, this is the third 3D ''Sonic'' game not to use the main theme song (or even a remix) for the final boss, the other two being ''[[Sonic Heroes]]'' and ''[[Sonic and the Black Knight]]''.
*Like the [[Wii]]/[[PlayStation 2]] [[Sonic Unleashed (Wii/PlayStation 2)|version]] of ''[[Sonic Unleashed]]'', while using the [[Boost]] on a [[Dash Panel]], Sonic performs a Spin Dash animation.
*In both ''Sonic & Knuckles'' and ''Sonic Generations'', the [[Death Egg]] can be seen in the background of Sky Sanctuary. In ''Sonic & Knuckles'', the next level is [[Death Egg Zone (Sonic & Knuckles)|Death Egg Zone]], and in ''Sonic Generations'', the next level is the fight against the Death Egg Robot, which coincidentally takes place in the Death Egg.
*The game's box artwork has a white colored accent on top and bottom.
*The rivals in this game appeared as playable characters in ''[[Sonic Rivals]]''.
**Knuckles is the only rival from ''Sonic Rivals'' that is a friend in ''Sonic Generations'', as the others are all rivals that battle Sonic.
*The drowning countdown starts at 4 instead of 5, although a different tone is played before the countdown starts. Underwater warning beeps are also much more prominent.
*After Sonic saves Tails, he makes a reference, saying that [[Green Hill (Sonic Generations)|Green Hill]] was "awfully familiar," followed by Tails saying that he doesn't recognize the stage at all. This most likely references the fact that Green Hill Zone is a ''Sonic the Hedgehog'' stage, and Tails was introduced in ''Sonic the Hedgehog 2''.
*This game takes place on June 23rd. The reason why is because one of the cutscenes shows Sonic's friends surprising him with a birthday party. In real life, June 23rd is the same day that the first ''Sonic the Hedgehog'' game came out. Its release date was June 23, 1991.  
*This is the second 3D ''Sonic'' game where Eggman is the final boss.
*Out of all nine main stages, three of the stages are based on the first levels of their respective games (Green Hill, [[City Escape (Sonic Generations)|City Escape]] and [[Seaside Hill (Sonic Generations)|Seaside Hill]]). To a lesser extent, [[Crisis City (Sonic Generations)|Crisis City]] is also considered a starting level in Silver's story, and [[Speed Highway (Sonic Generations)|Speed Highway]] is the first Action Stage in Knuckles' story in ''[[Sonic Adventure]]''.
*This is the second main 3D game to have someone (Classic Tails, specifically) call Dr. Eggman the name "Dr. Robotnik," the first being ''[[Sonic Adventure]]'', which was - in the English translation of the games - where Eggman got his nickname.
*This is the second 3D ''Sonic'' game in which the player starts a new game and are taken to the first stage, rather than showing the cutscene first. The first game to do this was ''Sonic Colors''.
*''[[History of the 1st Stage Original Soundtrack White Edition]]'' is the Japanese pre-order bonus for the game, not the soundtrack as originally thought. It compiles the first level themes of every mainline Sonic game.<ref>{{Cite web|title=HISTORY OF THE 1ST STAGE Original Soundtrack Blue Edition|url=http://vgmdb.net/album/28463|publisher=VGMdb}}</ref>
*Coincidentally, Shadow's line from his own game, "Where is that damn fourth Chaos Emerald?", is also referenced, as he has the fourth Chaos Emerald of the game.
*[[Takashi Iizuka]] said that the three original taglines for the game were "Blast with the past", "Déjà Blue", and "A speedy trip down memory lane".{{Citation needed}}
*With the exception of the [[Egg Dragoon (Sonic Generations)|Egg Dragoon]], all of the bosses in ''Sonic Generations'' only take half the amount of hits the bosses in the [[Nintendo 3DS]] [[Sonic Generations (Nintendo 3DS)|version]] can (four in the console/PC version, eight in the Nintendo 3DS version).
*In White Space, [[Sky Sanctuary (Sonic Generations)|Sky Sanctuary]] has trees with grapes in them. Knuckles' favorite food is stated to be grapes in the ''[[Sonic the Hedgehog 3]]'' manual, and Sky Sanctuary is also where Knuckles is saved in ''Sonic Generations''.
*When an "S"-[[Rank]] is achieved on one of the levels or bosses, the title of the stage in White Space changes from its original color to golden.
*The unlockable music list has slight remixes of the Classic Sonic songs (mainly ''Sonic the Hedgehog 3'' and ''Sonic & Knuckles'').
*After a stage is restored, a level's background noise can be heard, faint from the normal background music. This is easily heard when muting the music: 
**Green Hill: sounds of the waterfalls and bird songs are heard.
**Chemical Plant: sounds of construction are heard.
**Sky Sanctuary: loud bird songs are heard.
**Speed Highway: moving, honking cars are heard.
**City Escape: crowds talking are heard.
**Seaside Hill: sounds of a beach are heard.
**Crisis City: sounds of volcanic explosions are heard.
**[[Rooftop Run (Sonic Generations)|Rooftop Run]]: faint crowds are heard.
**[[Planet Wisp (Sonic Generations)|Planet Wisp]]: a mix of bird songs and construction is heard.
*The [[Death Egg Robot]] is the only boss originally fought by [[Sonic the Hedgehog|Sonic]] as himself. [[Perfect Chaos]] was fought by [[Super Sonic]] and the [[Egg Dragoon]] was fought by the [[Sonic the Werehog|Werehog]].
*This is the second game to use skill customization, the first being ''Sonic and the Secret Rings''.
*The PC version downloadable from Steam is always based on the PAL version, even in North America. This is confirmed due to "''Colors''" being spelled "''Colours''".
*During the credits, the original levels from each game play along with the music medley as a tribute to the original games. The following game versions were used: the original Japanese ''Sonic Adventure'' release on [[Dreamcast]], ''[[Sonic Adventure 2: Battle]]'', the PC version of ''[[Sonic Heroes]]'', the [[PlayStation 3]] version of [[Sonic the Hedgehog (2006)|''Sonic the Hedgehog'' (2006)]], the [[Xbox 360]] version of ''Sonic Unleashed'', and the Wii version of ''Sonic Colors''. There are no obvious indications if the Mega Drive games are originals or direct emulations (or even ''[[Sonic Jam]]''). Oddly enough, even though the credits use the revised Japanese version of the original ''[[Sonic the Hedgehog (1991)|Sonic the Hedgehog]]'', the unlockable emulation in console versions is the original American release.
*''Sonic Generations'' was held on a 66% discount on Steam via PC Download as a Daily Deal due to the large amount of downloads.<ref>{{Cite web|url=http://compsimgames.about.com/od/gamingtips/tp/Steam-Summer-Sale-2012.htm|archiveurl=https://web.archive.org/web/20120912071517/http://compsimgames.about.com/od/gamingtips/tp/Steam-Summer-Sale-2012.htm|archivedate=12 September 2012|title=Steam Summer Sale 2012|last=Marriot|first=Scott|work=About.com}}</ref>
*In the Collection Room, two of the cutscenes the player can view are both named "Eggman Abducted", both being the cutscene after beating the Death Egg Robot and the Egg Dragoon.
*The rival and boss battle of the Dreamcast Era mainly used the Boost throughout the fight which was introduced later in the series.
**In contrast, the rival and boss battle of the Modern Era mainly use the [[Homing Attack]] and [[Auto Running|Auto-Running]], which were introduced earlier in the series.
*Not long before the release date of ''Sonic Generations'', Sega sponsored a skateboarding sporting event that took place in Venice Beach of California named "[[Sonic Generations of Skate]]".
*The Silver the Hedgehog boss battle is the only recreated/reimagined boss in the game that was not based off a second-to-last or final boss. Metal Sonic, Egg Emperor, and the Egg Dragoon are boss battles that are second to last while the Death Egg Robot, Big Arm, Shadow the Hedgehog (final boss of Hero story in ''[[Sonic Adventure 2]]''), and Perfect Chaos are all final bosses to their story modes and games.
*When looking at the models on the character profiles, both Silver and Rouge strike the same poses.
*If the player views the entire White World in a 3D model viewer, if they zoom out and look around, the entire Crisis City level will be there.
*Despite the game giving Super Sonic a theme, (it being an instrumental remix of the ''[[Sonic the Hedgehog 4: Episode I]]'' theme) it only plays during the final phase of the Time Eater boss fight, and a variant of it plays in the cutscene prior to the fight.
*When booting up the PlayStation 3 version of this game, some of Sonic's sprites from the original ''Sonic the Hedgehog'' are used before the Sega motto loads up.
*The physics engine is actually a modified version of the ''Sonic Unleashed'' engine. Hacking into the game can restore properties found within ''Sonic Unleashed'', including light shafts, motion blur, and directional shadows.
*On 14 July 2015, Sega posted a video of the cutscene played before the final battle, adding in footage from a motivational speech video featuring actor Shia LaBeouf. That speech came from ''#INTRODUCTIONS''.<ref>{{Cite web|author=Sonic the Hedgehog|title=Sonic Generations - Shia LaBeouf DLC (Spoilers!)|url=https://www.youtube.com/watch?v=Xhsj9J0BbqM|work=YouTube|date=14 July 2015}}</ref>
*In the "Ending" cutscene, the dialogue between both [[Miles "Tails" Prower/History and appearances (1992 - 2006)|Classic]] and [[Miles "Tails" Prower|Modern Tails]] is different between the English and Japanese scripts. In the English script, Classic Tails asks Modern Tails where Sonic puts all of his collected Rings. In the Japanese script however, Classic Tails asks his Modern self how he could add legs to Sonic's [[Cyclone|Tornado model]].
*''Sonic Generations'' is the fourth main game to have all four hedgehog main characters presented (Sonic, Amy, Shadow and Silver). The others before this being ''Sonic the Hedgehog'' (2006), ''Sonic Rivals'' and the [[Nintendo DS]] [[Sonic Colors (Nintendo DS)|version]] of ''Sonic Colors''.
*This is the only game dubbed in French, Spanish, German, and Italian to not have the Wisp announcer voiced in those languages, with the game using its English voice instead.
*Aaron Webber mentioned in an interview that if anyone were to voice Classic Sonic, his personal favorite would be [[Jaleel White]].<ref>{{Cite web|author=Black Nerd Comedy|title=E3 2011 HAPPY BIRTHDAY SONIC! with StarSlay3r & Mo Chocolate - Black Nerd E3 (Part 4)|url=https://www.youtube.com/watch?v=Kt6w7og5UMk&t=129s|work=YouTube|date=23 June 2011}}</ref> Aaron also mentioned that he grew up with the classic Sonic cartoons, and he thought Jaleel White did a fantastic job.

*This game contains the second highest polygon counts for a [[Sonic the Hedgehog|Sonic]] model, with the Modern Sonic model reaching 16,173 tries, 16,173 faces and 8,316 verts. The highest polygon count so-far is the one from ''[[Sonic Unleashed]]''.<ref name="Low Poly">{{Cite web|url=https://www.youtube.com/watch?v=Z_Pvr7Cc2Ds|title=Sonic The Hedgehog - Low Poly (Evolution of Characters in Games) - Episode 2|last=Collins|first=Andy|date=22 April 2017|accessdate=20 September 2022|work=YouTube|quote='''[[Andy Collins]]''': This model is 16,173 tries, so roughly 3,000 tries less than the one in Unleashed.}}</ref>

*So far, this is the last mainline Sonic game to physically feature Cream and Blaze.
*This is the first mainline Sonic game since [[Sonic the Hedgehog (2006)|''Sonic the Hedgehog'' (2006)]] to feature [[Knuckles the Echidna]].
*One of the most widely spread rumors about the game was that a third Sonic, who would’ve represented the "Dreamcast Era", was planned to appear in ''Sonic Generations'', with [[Ryan Drummond]] returning to the voice the character. This all comes from an interview where Drummond reveals that he was offered the chance by SEGA to re-audition as Sonic during the development of ''Sonic Generations'',  but he would eventually decline due to his distaste for the contract.<ref name"rdinterview"="">{{cite web |url=http://www.thegamingliberty.com/2012/09/sonic-the-hedgehog-speaks-an-interview-with-ryan-drummond/ |archiveurl=https://web.archive.org/web/20150101020908/http://www.thegamingliberty.com/2012/09/sonic-the-hedgehog-speaks-an-interview-with-ryan-drummond/ |archivedate=1 January 2015 |title=Sonic the Hedgehog speaks!

**For years, fans would use this interview to back up the existence of a third "Dreamcast Sonic", this was all just a rumor however, as Drummond was simply re-auditioning for the role of Modern Sonic back in 2010 after the ''Sonic X'' cast’s contracts expired. Additionally, no veritable sources nor Drummond himself have ever said he was voicing a third Sonic.<ref>https://twitter.com/thekevineva/status/1682024740297523203</ref>
