You would think so lol, but no, Xbox 360. I'm in now, you can link your accounts to the website, I think there's some bonus in doing that. Has to be said there's a lot of messing around just to get up and running. The servers are down atm and I can't get in, not the best start I guess!
You're not gonna tell me their servers are overloaded due to the high demand on day 1... surely not.
