Haha. You can play the game on your friends xbox if you SIGN IN. How long will the gamer tag recovery take? As long as the current one? We had a 360 set up in the college student room and anytime my friend and I wanted to play a xbla fighting game like street fighter 3 or whatever we'd have him long into his account and it'd take five or ten minutes before he recovered the account, and that was after the first time when we had to dl the game.
So it is basically THAT but with physical discs and instead of dling it has to install.
