So i got a chance to play it for the first time for about half an hour at Gamestop. At start, the game looked fine. But the controls were clunky, the framerate slipped (even on Gamestop's HDTV), and the story didin't make any sense. For me, a sonic fan since playing it on the genesis and 32X, this game was underwhelming.
For those of you planning to get it: don't.
