If only it had more levels and better cutscenes, then. It would be perfect!
here's the summing up:
graphics: Nothing reveloutionary, but some pretty good graphics for the wii unlike others (I'm looking at YOU my pokemon ranch). 8.5/10
gameplay: The best part of the game. Although it takes a while to get sonic moving fast, when he does... HE GOES FAST! which is but one of the good things in this game. The levels are really imaginative and some of the best i've seen in a sonic game. The enemies aren't all of Eggman's robots which is good for a change. There are loads of missions to do and there's also a party mode! 10/10
sound: The sound is very good in this game, enough said.
8.5/10
music: Apart from the main theme tune, there are some very good songs in this game!
8.5/10
Story: The story is quite good but I don't really like the style of the scenes in this game. 7/10
overall: I would easily reccommend this game to any sonic fan!
