Worse than the HD version (obviously). Having both Classic and Modern Sonic be 2D really does detract from the experience, and almost makes you wonder why they made the game at all. They try to do this thing where you unlock new moves throughout the game, but why keep Modern Sonic from getting the stomp until the game's nearly over already? And, come on, why are we giving Classic Sonic the homing attack? The best thing about the game is shared in common with the HD version: visiting all these old locations from past Sonic games, and there really is charm in that. But playing throught the game... eh. Just another mediocre Sonic game.
