Sonic Origins

This is an excellent remake of the Sonic 1-3 with knuckles & Sonic Cd. It has plenty of modes to play this, Anniversary mode, Classic, Mirror & boss Rush. They fixed the glitch of dying on the spike in part 1, Updated graphics for Sonic 2's bonus stages, they look a lot better. You can now play Tails & knuckles in Sonic 1 & play Tails in Sonic Cd. However because it lacks save states & a rewind feature just play these games on original hardware except for Sonic cd.
