I really do love Mario 3D platformers, but I got burned out on it about the time of Galaxy 2.
The Sonic franchise games that were on Nintendo systems. Not... all of them, but I like Sonic Adventure 2 Battle, Colors, Secret Rings, Black Knight, Unleashed (though I haven't bothered to finish it). They're alright, I like Colors the most.
Oh, gosh. Epic Mickey. I loved Epic Mickey, and it almost slipped my mind for some reason. I think it was a brilliant return for Oswald and I found the game challenging enough to be interesting, and while kinda dingy at times, it worked very well for the setup of the game.
