Editing Sonic Unleashed (section)

==Trivia==
*''Sonic Unleashed'' was originally going to be titled ''Sonic Adventure 3'', until the team decided to make this game more focused on Sonic.
*This is the last mainline ''Sonic'' game to feature the [[4Kids Entertainment]] voice cast (sans [[Mike Pollock]]).
*''Sonic Unleashed'' is the third ''Sonic'' game to receive a rating of E10+ from the [[Entertainment Software Rating Board|ESRB]].
*The game's art direction and cut-scenes are widely inspired by animations of the [[Wikipedia:Pixar Animation Studios|Pixar Animation Studios]], which explains why the humans have a cartoony appearance in contrast to the [[Sonic Adventure|anime-styled]] or [[Sonic the Hedgehog (2006)|realistic]] looks from the previous games.
*A [[PC]] port of the game was planned but later scrapped for unknown reasons. However, some ported files can be found in the PC version of ''[[Sonic Generations]]'', such as button hints at loading screens, images of purchasable goodies, Sonic and Werehog life icons, and an uncompleted renderer which is capable of rendering directional shadows.

*The cover artwork was originally going to use [[wikipedia:Lenticular printing|lenticular printing]] to have Sonic turn into the Werehog. For unknown reasons, the idea was scrapped and the two were split in half instead.<ref name="LenticularCover">https://www.instagram.com/p/B5Jemp8nUs3/</ref>
*In previous years, it was rumoured that the lead actor [[Jason Griffith]] was sick during his recording sessions and recent confirmed in a 2023 panel.
*Between the HD games, the PlayStation 3 version runs faster at 60fps rather than a capped 30fps, but still retains the same frame rate dips as the Xbox 360. However several instances run much smoother on PlayStation 3, such as The daytime Windmill Isle and Cool Edge stages and the Tornado Defense stage. Certain special effects such as Sonic's speed dust particles are also enhanced on PlayStation 3, though miscellaneous details such as windmills in the distance are missing. Character models are very slightly enriched on the PlayStation 3, while the Xbox 360 employs smoother shading. The transition between day and night was also changed to be a silent screen showing the Sun and Moon medals for the PlayStation 3 version rather than Sonic's transformation. Between the Wii and PlayStation 2 games, the Wii version is generally regarded as graphically superior, as the PlayStation 2 version has fewer polygons and dimmer lighting. However the PlayStation 2 version has far more responsive controls than the Wii, as the Wii version suffers from eight directional movement (a common issue with ''Sonic''{{'}}s GameCube and Wii ports), basic punches with the werehog also requires you to hop between two buttons, while PlayStation 2 only requires one button.
**With the FPS Boost support for the Xbox Series X/S, the framerate for the Xbox 360 version is now a capped 60fps when enabled.
*Sonic's model in the Xbox 360/PlayStation 3 version of the game is made up of 19,887 visible polygons, or "tris", which made it the most high-definition model of Sonic until ''[[Sonic Forces]],'' which was later surpassed even further with the model from [[Sonic Frontiers]].
*When booting up the PlayStation 3 version of this game, some of Sonic's sprites from ''[[Sonic the Hedgehog (1991)|Sonic the Hedgehog]]'' are used before the Sega motto loads up. This happens again in ''[[Sonic Generations]]''.
*The trophy/achievement, "I ain't afraid of no ghosts," is a reference to the ''[[Wikipedia:Ghostbusters|Ghostbusters]]'' theme song.
*This is the first ''Sonic'' game where Sonic can collect at least 1,000 or more rings in a stage (daytime), as other games' ring cap limit is 999.
*Though it is the first 3D game to use the Boost, it is actually the third main game in the series to use it overall; following ''[[Sonic Rush]]'' and ''[[Sonic Rush Adventure]]''.
*In the opening cinematic, a [[Dreamcast]] console can be spotted when Dr. Eggman pushes the button to fire the laser. It is seen again later when the Egg Dragoon is defeated. In the cutscene where Sonic loses his Werehog transformation, a Dreamcast can be seen to the left of Dr. Eggman. The Dreamcast also makes an appearance in the scene after the Egg Dragoon is defeated; when Dr. Eggman is seen attempting to command Dark Gaia to destroy Sonic, the Dreamcast, along with a controller and a game case (with Dr. Eggman's 2D art for ''Sonic Rush'' as the cover) can be seen to the right of Eggman.
*In the PlayStation 3 and Xbox 360 versions of the game, in the nighttime Spagonia HUB to the right in a small lane, a person in the shower can be heard whistling the theme from the teaser trailer.
*This is the first game in the main series to be known by a different name in Japan, where it goes by the name ''Sonic World Adventure''. The next is ''Sonic Generations'', which was given subtitles based on the consoles it was released on.
*This is the first ''Sonic'' game from the main console series since ''[[Sonic Adventure]]'' not to have [[Crush 40]] perform the theme song.
*This is the first main series game to not feature [[Knuckles the Echidna]] since ''[[Sonic the Hedgehog 3]]'', and the first console game to not feature [[Shadow the Hedgehog]] since ''[[Sonic Adventure 2]]''.
**It's worth noting that they were planned to appear in the game, but were later scrapped.
*There are some level segments that are not used in the game's final version, though they can still be accessed in the Xbox 360 version of the game with glitches. These areas were later recycled as levels for the DLC Adventure Packs. A number of changes were also made in these areas, which can be seen by people not owning the DLC and using the Werehog's [[combo]] trick to access them:
**Jungle Joyride Act 1 (Night): After the Goal Ring in Jungle Joyride's main Night stage, there is a sealed door. By using the wall-walking glitch, it is possible to cross through this door. There is a large, unused, empty chamber within. If accessed from the ghost mission instead of the main level, the door will be open, and there will be objects inside. There is a tree which can be knocked down and used as a bridge, floating platforms, and switches that raise the water level. The platforms and the kill zone raise, but the room's unique water level puzzle is clearly unfinished- the water graphics remain in place. At the top of the room, there is a door. Beyond the door is an ornately detailed chamber containing the original Goal Ring.
**Arid Sands Act 1 (Night): After the Goal Ring in Arid Sands' main Night stage, there is a sealed door. By jumping onto it from a well-positioned water barrel and using the uppercut, followed by the midair {{Triangle Button (PS)}}{{Triangle Button (PS)}}{{Cross Button (PS)}}/{{Y Button (Xbox)}}{{Y Button (Xbox)}}{{A Button (Xbox)}} combo, the player can fall into an unused canyon area. It's empty, but the player can open the sealed door from the other side. The player must bring water barrels to the bottom of the chasm, stack them, and perform an uppercut-grab to go on. There is a huge chunk of level which is empty. Inside it is, among other things, two pillars the player can knock down which don't appear elsewhere. Eventually, they will reach a pit, which cannot be crossed without objects to bridge the gap. Beyond it is a fairly large stretch of level that leads up to the Gaia Temple.
**The Nighttime levels of Skyscraper Scamper and Dragon Road also contain such areas. The former also has a [[:File:Werehogjavelin.png|javelin throwing gameplay gimmick]] for the Werehog, which was never finished entirely and therefore does not function properly. This gameplay gimmick was never recycled for the area's corresponding Adventure Pack DLC either, and was left unfinished. It can be found in the mission called 'Play It Cool'.
*Tails, Amy and Professor Pickle do not seem to have been affected by Dark Gaia. The Professor even remarks that he knows his assistant is affected by Dark Gaia, and that he must do something to help him.
*The manual incorrectly states that the {{L2 Button (PS)}}/{{R2 Button (PS)}} // {{LT Button (Xbox)}}/{{RT Button (Xbox)}} are not used in the day stages, but they are used to perform the [[Drift|Sonic Drift]].
**It is also stated in the day stages section of the manual that if Sonic doesn't reach the goal within 10 minutes, he'll lose a life. This isn't true in the game itself, meaning the player can take as much time as needed to clear a day stage. This is a reference to the classic ''Sonic'' games and also ''[[Sonic the Hedgehog 4]]'', where the player has to finish each act within ten minutes.
*One cutscene contains a reference to the ending of ''[[Sonic the Hedgehog CD]]''. The cutscene plays after the first exorcism of the game. During the cutscene, Sonic (in his Werehog form) is seen carefully putting Amy on the ground after having saved her, with her eyes closed, then quickly leaving by swinging across buildings when she opens her eyes and turns to look at him. Much like how in the ending of ''Sonic CD'', he put Amy on the ground, and then, while her eyes were still closed, he carefully backed away and then ran off just as she opened her eyes.
*In the Xbox 360 version, after Perfect Dark Gaia is defeated and the earth is returning to normal, Chip says, "Sonic, You '''must''' live." while the subtitles say, "Sonic, You '''have to''' live.".
*This is the only ''Sonic'' game where Sonic never loses the Chaos Emeralds throughout the game.
*On the official website, the rating in the trailer showed is E10+ but the audio is the "E for everyone" rating clip.
*In the [[Android]] and [[iOS]] versions of  ''[[Sonic & Sega All-Stars Racing]]'', there is a mission called "Sonic Unleashed" where the player plays as Sonic to destroy wolf-like robots, referencing Sonic's Werehog form.
*In the PlayStation 3/Xbox 360 version, there are two trophies/achievements named after songs from the British band [[Wikipedia:The Beatles|The Beatles]].
*This is the final main series ''Sonic'' game on the [[PlayStation 2]], as well as the last ''Sonic'' game to be released on a 6th generation console.
*This is the second game to have a different level entrance screen than the rest of the ''Sonic'' games. The first was ''[[Sonic Adventure]]''.
*In the demo version of ''Sonic Unleashed'' on the Xbox 360, the game will read ''Sonic World Adventure'', the Japanese title and list a Japanese URL.
*Dr. Eggman's artwork for this game has the same pose as his artwork in [[Sonic Channel]].
*If the player looks around "BONNY'S KITCHEN" in the [[Empire City]] HUB closely enough, there is a magazine named "WORLD TREASURE" on the cover that appears to be [[Shamar]].
*The trophy/achievement "Pig in a blanket" is a reference to a traditional European snack of the same name, consisting of sausage wrapped in bacon.
*In the cutscene "A New Journey" when Sonic looks around after the fall, if one looks at the Chaos Emeralds in the shot, they will see the purple emerald has still got its color.
*As of December 2009, ''Sonic Unleashed'' was labeled as an "Xbox 360 Platinum Hit" and has the "Xbox 360 Family Games" label after selling over three million copies. It was labeled as an "Xbox 360 Classics" title in PAL regions. Although ''Sonic Unleashed'' did not sell well enough to become a "PS3 Greatest Hits" title in the NTSC region, it sold enough copies in the PAL region to become a "PS3 Essentials" title.
*The daytime level theme for [[Savannah Citadel]] has a similar melody to the opening of the end credits medley for [[Sonic the Hedgehog (8-bit)|''Sonic the Hedgehog'' (8-bit)]].
*This game shared a few things in common with ''The Legend of Zelda: Twilight Princess'':
**Both the main characters turned into a wolf-like being in numerous points in their respective game (Link becomes a wolf when he's in the Twilight Realm and Sonic becomes a Werehog at night)
**Both main characters were accompanied by a small flying supporting character who is important to the storyline (Midna for Link and Chip for Sonic).
**Both games have a character who suffered amnesia (Ilia and Chip)
**Both games have a major antagonist alongside the series overall antagonist (Zant/Ganondorf and Dark Gaia/Dr. Eggman). The difference being that Zant is the penultimate boss before Ganondorf while Dark Gaia is the final boss after Eggman.
*This game contains one of the highest polygon counts for a [[Sonic the Hedgehog|Sonic]] model in the entire series, with the said model reaching 19,887 tries, 19,887 faces and 10,389 verts.<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|publisher=A+Start|quote='''[[Andy Collins]]''': As polarizing as this game can be, it's actually got one of the most well made Sonic models in the entire series. It's made of a staggering 19,887 tries, making it the highest polygon count Sonic model to this day. No other Sonic model even comes close to this amount of tries.}}</ref>
