hopefully you have better luck with it than I did with the 360 version. my copy wouldn't load past the main credits and Amazon still hasn't got back to me regarding exchanging it. good thing i also have the ps3 set which I heard also has issues that luckily I haven't encountered yet.
I haven't heard of any issues. Is it freezing up on people while loading? Any other issues i need to know about? Going to have to check mine out tonight to make sure its ok.
