I own Mario And Sonic At The Olympic Games(1 not Winter) but besides that I have yet to buy a Sonic game on the Wii. I own many Sonic games on the Gamecube though and my favorite my far is Sonic Adventure 2 Battle but that could have a lot to do with the Chao things. Anyway this gen Sonic has been looking horrible but Sonic Colors looks like it could be my 1st Sonic game this gen!
