Mania's not really doing it for me. I'd rather they do a sort of Sonic 3D Land with more-frequent-yet-smoother-and-more-subtle transitions between 2D and 3D areas and the return of Amy and Cream as playables. Plus, ditch Sonic's Homing Attack for anyplace walljumping. That was the one major thing Sonic 3 & Knuckles was missing.
