Editing Sonic Generations (Nintendo 3DS) (section)

==Trivia==
*The internet poll asking fans what their favorite stages from each mainline ''[[Sonic the Hedgehog series|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 not announced yet at the time the poll was released, none of its stages appeared in the poll.
*This is the first ''Sonic'' game for the [[Nintendo 3DS]].
*This is the first ''Sonic'' game to have stereoscopic 3D capability.
*This is the first handheld ''Sonic'' game on a Nintendo console that features fully rendered 3D stages and dynamic camera angles.
*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''.
*[[Miles "Tails" Prower|Classic Tails]]' artwork seems to have "buckles" under his socks (above his shoes).
*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 the 3DS version, he spins simply from touching Dash Panels regardless of initial speed and can defeat enemies during the roll.
*This is the first time Modern Sonic gets Boost Energy from both [[Ring]]s and Enemy Power in a handheld console.
*The console/PC versions have a white colored design on top and bottom, whereas the 3DS version has a blue design. Likewise, the HD and 3DS' version's Japanese names are "White Time and Space" (console/PC) and "Blue Adventures" (3DS).
*The rivals in this game appeared as playable characters in ''[[Sonic Rivals]]''.
*In the console/PC version, the drowning countdown starts at four instead of five. In the 3DS version however, the countdown starts from the traditional five.
*The second era is the only era in which Dr. Eggman is not a boss.
*If a Ring Item Box is destroyed in the console/PC version, the sound when the player gets a Ring sounds ten times instead of one. In the 3DS version, however, it only just sounds once.
*Out of the seven stages in the game, four of them are the first ones in their respective original games, those being [[Green Hill (Sonic Generations)|Green Hill]], [[Mushroom Hill]],  [[Emerald Coast (Sonic Generations)|Emerald Coast]] and [[Tropical Resort (Sonic Generations)|Tropical Resort]] (assuming [[Sonic & Knuckles]] is treated as its standalone form, as this game does).
*Classic Metal Sonic's artwork pose is similar to Shadow's.
*This is the first handheld ''Sonic'' game in which the player starts a new game and are taken to the first stage, rather than showing the cutscene first.
*In the 3DS version, Classic Tails suddenly appears after the boss battle with the Death Egg Robot/Big Arm. [[Takashi Iizuka]] said that there was going to be an explanation but it never got worked into the game's story, and he wanted to leave it open to the fan's opinion.
*''History of the 1st Stage: White Edition'' and ''History of the 1st Stage: Blue Edition'' are the Japanese pre-order bonuses for the console/PC and 3DS versions respectively, not the soundtrack as originally thought. They are both disks with separate soundtracks that consist of music from the first stage of the franchise.<ref>{{Cite web|title=HISTORY OF THE 1ST STAGE Original Soundtrack Blue Edition|url=http://vgmdb.net/album/28463|publisher=VGMdb}}</ref>
*[[Takashi Iizuka]] said that three original taglines for the game were "Blast with the past," "Déjà Blue," and "A speedy trip down memory lane."
*While the console/PC version has a level from ''Sonic Heroes'' as part of the second era (Seaside Hill), the 3DS version has a stage from it part of the third era (Egg Emperor). In the 3DS version, ''Sonic Heroes''<nowiki>'</nowiki> stage representation is spread throughout the eras as the game's Special Stages.
*With the exception of the [[Egg Dragoon (Sonic Generations)|Egg Dragoon]], all of the bosses in the console/PC version can only take half the amount of hits the 3DS version's bosses can (four in the console/PC version, eight in the 3DS version).
*The console/PC version of the game had [[Speed Highway|the highway stage of ''Sonic Adventure'']], and [[City Escape|the first stage of ''Sonic Adventure 2'']]. The 3DS version is the opposite; it has [[Emerald Coast|the first stage of ''Sonic Adventure'']], and [[Radical Highway|the highway stage of ''Sonic Adventure 2'']].
*On the console/PC version, Classic Sonic and Modern Sonic fight each rival ([[Metal Sonic]], [[Shadow the Hedgehog]], minus [[Silver the Hedgehog]]) in the areas Sonic fought them in the original games, but the 3DS version has Sonic fight them in areas he did not fight them in the original.
*The launch trailer for the 3DS version has a small mistake. During the Modern gameplay showcase, a clip from Classic Water Palace is shown.
*The 3DS version is to date the third game to feature monitors (instead of capsules or nothing) in Modern Sonic's stages. The first game was ''[[Sonic the Hedgehog Pocket Adventure]].''
*Both City Escape and Radical Highway are the first stages for both Sonic and Shadow in ''Sonic Adventure 2'' respectively. Both stages represented the second era.
*In the console and PC versions, it takes about five seconds for Classic Sonic to get impatient and 35 to lay on the ground. However, in the 3DS version, it takes 30 seconds for him to get impatient and a whole minute to lay down.
*This is the first modern ''Sonic'' game on a handheld Nintendo system not to have [[Boost Mode]]. It is also the first where boosting through enemies is "seamless," not causing a split-second pause like in ''Sonic Unleashed ''(Wii/PS2) or the DS games.
*In the console/PC version, Omochao works as a guide by advising the Sonics, while in the 3DS version, Tails is the one giving advice (Classic Tails to Classic Sonic and Modern Tails to Modern Sonic).
*In the 3DS version, Classic Sonic's model becomes shinier when the player turns on the 3D effect.
*Orcas appeared in both versions of the game, in Seaside Hill (360/PS3/PC) and Emerald Coast (3DS).
*In the 3DS version, if Sonic gets a standard shield while having a Thunder one equipped, he will keep the Thunder shield instead of switching to the standard one.
*In the 3DS version, many of the stages remake their original layouts. Act 1 of Green Hill, Casino Night and Mushroom Hill are directly copied from Act 1 of their respective originals. Act 2 of Water Palace and Act 1 Tropical Resort are not exact copies and do feature new areas, but have the majority of the stage be a loose remake of Act 1 of their respective originals (the Nintendo DS version of Sonic Colors, in Tropical Resort's case).
*Time Eater being initially believed to be the main antagonist only for Eggman to reveal himself as the true main antagonist near the end is a reverse twist to most 3D ''Sonic'' games; in which Eggman is initially believed to be the villain only for another enemy to be revealed as the true enemy towards the end.
*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.
*In the 3DS version, the main menu's music is the title screen from ''Sonic Mega Collection,'' and White Space theme is the main menu theme from ''Sonic Heroes''.
*On the 3DS version's Profile Card patterns, the screenshot used for "Sonic Unleashed" comes from the Wii version, not the console/PC version, modified to include a directional shadow.
*This is the only ''Sonic'' game to have the [[Cyan Laser]] exclusive to a handheld game instead of appearing in both the home console and handheld.
*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.
**When announcing the Cyan Laser, the announcer uses its voice clip from the Nintendo DS version of ''Sonic Colors'', rather than the Wii version.
