When you first played Epic Mickey, it was a one-of-a-kind experience, huh? Well, not so much! Apparently there was an old game called Mickey Mouse Mania in which Mickey goes through a bunch of old cartoons to save his former incarnations. It's a visually beautiful game, and for the SNES, it's incredible.
But what makes it like Epic Mickey is the classic cartoons. Many of the projectors in EM are similar to Mania's, and the Mad Doc is even a boss! If you've got an SNES or Sega around, you should definitely try this rare masterpiece. It's a lot like the more well-known Castle of Illusion.
