Ugh...don't get me started about this game. Don't get me wrong, this game isn't totally awful. I mean the graphics are fanatastic, so much better that those of the Gamecube Sonic games. But with that said, they were Dreamcast ports. The voice acting is so-so. You get the semi-good Sonic X voices. I personally switched to the Japanese ones cuz I like them better.
The thing that ruins this game from being the bast game on the Wii...is the crappy tility controls and the fact that its "on-rails". By that I mean there's no freedom to run where ever you want like previous Sonic games. You have to go where the course takes you, which I hate. I know that's how most stages in Sonic games are like, but not like this one. I would have much prefered this game with the Wii-mote and nunchuck.
