What a horrible list! Spin-off titles like Tennis and Mean Bean should never be in a Sonic top ten because they ain't Sonic games! If they don't follow the gameplay rules and mechanics of a Sonic game, then they're not a Sonic game. They're spin-offs featuring Sonic in another genre. Admittedly, SST and Mean Bean are good games but they hardly classify as Sonic games. They're closer to being Virtua Tennis and Puyo Puyo titles respectively.
Not a single 3D title on the list? 8 of the 10 titles are 2D Sonic games, so the dumbfuck might as well just replaced SST and Mean Bean with two 2D Sonic games and called it his top ten 2D Sonic games list.
Only thing I agree with are most of his comments on Sonic 4. Though I would swap Sonic 1 and Sonic 4 and wouldn't include Colors DS because I've never played it.
