There were originally plans to have Knuckles' Chaotix and SegaSonic the Hedgehog included in the game. The only remnants of Knuckles' Chaotix is in the game's art gallery, and SegaSonic the Hedgehog was cut due to problems with emulating the game's original trackball control scheme.

In the Museum of Sonic Gems Collection, a number of classic Sonic games can be unlocked. These games start at the final boss, and can only be played for a set amount of time.
By using a cheat device to freeze the clock it's actually possible to play the entire game after the final boss is defeated.
