I generally like Sonic games, particularly 2, 3&Knuckles, 3D Blast, Adventure, Heroes, and Rush. I've backed away from Shadow, Riders, and HD more for the reason that I don't like they company's direction rather than the games themselves. Sonic Adventure hasn't aged well, so I see little hope in future 3D Sonics with the same mechanics.
SatSR has me intrigued. SEGA finally has a novel idea down that seems as simplistic as the Genesis titles. I'm purchasing this title day one without question.
