not that great
the controls were all right, nothing real fansy or difficurt, the main thing, for me at least, was just timing your jumps over obsticals. i had a lot of moments where i couldnt make the jump and kept having to start back over to miss the jump again.
the graphis were non-the-less impresive, the game looked great. and the camera was more or less coroperative. alot better than sonic on the 360 nad ps3. the rear view camera was well done, unlike the 360 and ps3 version, but the levels had you only going forward, instead of giving you levels that you can run around and explore.
all in all its a game sonic fans may want to rent just to say they played it.
