 * Because of this, Empire City was given a Gaia gate and additional Challenges, and Mazuri's was redesigned to have doors for its stages.
 * The Wii/PS2 version's Day Stages are "Act 1", and the PS3/Xbox 360 Version's Day Stages are "Act 2".
 * The same thing Applies to the Night Stages, however the Wii/PS2 version's stages are no longer split up, and are combined all into one Act.

 * Sun and Moon Medals are now used to unlock extra Missions and Stages instead of being required for stage progression.
 * The Story has been slightly changed in some aspects.
 * Empire City is given a reason to be visited, as Shadow the Hedgehog and Knuckles the Echidna are defending the city.

 * The Final Boss is a fusion of both versions as well, now having 5 Phase. The Gaia Colossus charging section, then the "Punch-Out!" section, then the Sonic Section, then the PS3/Xbox 360 Super Sonic section, and finally the Wii/PS2 Section.
 * Due to Eggmanland's Different Level Layout, Wii/PS2 Day Stage is Act 1, the Night stage is Act 2, and the PS3/Xbox 360 Stage is Act 3.
 * Due to the better Processor, the game no longer has framerate issues, and runs at a consistent 60FPS.
 * All of the Werehog's Battle themes are now Remixes of the Stage he's currently in, with the basic Battle theme being for Empire City.
