For those of you who own the full game and are considering getting XBOX Live, it's a good option, but so you know, you will only be able to access LIVE from the disk that comes with your xbox live kit. Essentially, if you turned around and traded your original in toward the purchase of Moto GP 2, you could still play live with all your unlockables, but it may be a good idea to backup your memory save in case you lose it somehow. I suppose if someone had action replay, they could turn around and download a full save with everything unlocked and use it with everything unlocked on Live. That's just what I'm assuming from the setup of it all of course. It would be nice to get some feedback to see if anyone's been successful with it.
