If you buy new you can be sure that there will not be a problem, but if you know the right stores buying used is just as great. You can always go to gamestop and buy the used game there. I have gotten many games there that were used and I have only once had a problem. The problem was that the game was scratched and it would not run, but gamestop took it back and gave me a new, used one, for no extra charge.
