Nah, with that much amount in fan service in the game, a fleshed out single player experience, and oodles and oodles of replayability, I'd say that it's a game that delivered on its promises.
Well, I do have two small gripes... one would be tripping and I just wished they did more with the online aspect of the game. Maybe next time...
Oh! Knuckles and Ridley need to be in the next one.
