The Wii version is much better though, in my opinion. It’s the first 3D Sonic game I’ve ever liked. I think I’ve put about 4 or so hours into it now, mostly replaying the early stages to try and get the S rank and find all the red rings. I think there’s a pretty great incentive to find all the rings too, since they unlock these 2D levels with awesome 8 bit covers (http://www.youtube.com/watch?v=QQAx4zH4c9c) of all the main themes in the game. Most of the soundtrack is really good though, except the two dreadful rock songs with lyrics by Cash Cash. The game is also really pretty (http://www.youtube.com/watch?v=o2ZDby6iYqE). There seems to be a lot of inspiration from Super Mario Galaxy in Sonic Colours’ representation, which is not a bad thing.
I think I’ve sold it about as best I can. I’ve never been a fan of the series so I’m kind of excited I’ve found a Sonic game I think is really fun. Everybody should go try it out.
