A very fun game that has to do with teamwork! I don't understand why they didn't make it co op, but it's still fun playing both single and 2-player modes. It's also one of my favorite Sonic character's debut! E-123 Omega! I still think they should have put Mighty in the game, I don't know why they had to kick him out when he's a member of the Chaotix. And shouldn't Knuckles be in Team Chaotix, too? I still think this is better than many of the new Sonic titles, and, although the graphics aren't PS3 amazing, they're good for a PS2 game. The game's good for a Sonic fan at any age, you don't have to be a hardcore video gamer or a Sonic fan to love this game (although I'm both ^_^).
