game play 10/10
Total 9.5/10
so that is why i give this game a 9.5. multilayer is ok not that great. this is better than some other sonic games! this game is a really good game. You collect a lot of chaos emeralds to unleashed sonics ultimate power. this game is exciting and fun. they should have it for other consoles or like xbox live arcade or something like that.
buy it... play it... love it...
