Dope idea, but the price...gotdamnit the price. This is something that should be free to gold subscribers, because I can take those same 400 MS points and drop it on something a bit more "substantial" than Motherfucking Sinistar on XBL Arcade.
They need to bring Double Dragon back. I downloaded it once and got the RROD. Got my shit back and the game was gone. Then found our a year later you can re-download your games if you lose them. But this sounds like a great idea though. Cant wait to see how it works. It would be cool if they had different avatars at the machine playin makin it feel realistic
