I'm moving to the US next month from the UK and was wondering if I'll be able to take my trusty 360 with me. Will I be able to play games I buy in the US with it? I'd rather not have to buy a new one but if I have to I will as there's a lot of games coming out in November thatI want to get my hands on. Also buying a new one would be inconvinient because of all of my old games I still play.
