[quote name='Gosha']I'm holding out for $15 on this game. I think it'll hit that within the next month. I already have the DS version, which is somewhat similar.[/QUOTE]
Very different games. The DS version is essentially Sonic Rush 3 with a few details changed to fit the Colors "theme" (but not even close to the point of identity...)
Anyway, this is a great price for the game.
