yeah i play the original fable on my 360 and i get glitches too. sometimes for no reason at all my skin will turn green in some parts and also, newly loaded areas make the game run really slow until it finishes loading...while i'm in it lol. also the 360 is quicker to decide that your disc is dirty or damaged. i don't know how many of those things apply to it but it's not a problem, it's the crappy emulating technology that microsoft put into the 360, i wouldn't worry about it too much, just download update after update for your xbox and hope it gets better
