I dunno if its my 360 or my rainbow 6 vegas cd but randomly the disk will stop spinning sometimes and says it can't be read which pisses me off in the middle of online play and it pretty much happens every day. However, i simply life the disk out, put it back in and it works fine after for the rest of the day or w/e. Doesn't happen with other games i have, only once with fifa 07 but i dunno. Other flaws? mythumb slips off sometimes when playing fifa 07 coz the controllers a bit big or spaced out on the analog sticks. I love it though.
