Been playing since the day before on the One X and I don't have a single problem with it, ok it crashed completely once, but it isn't the only game to have done this and a couple of graphical glitches, again nothing new in any game really. Used to seeing items pop up on the screen as it redraws it. Agree it needs polishing but it isn't that far away.
The gameplay is excellent, the graphics do look great. My only annoyance was during a load of cut scenes before Act 1 where it all goes wrong, it spent 10 seconds loading a cut scene that lasted for 5 seconds, and did this for what seemed like ages.
