Yea I just bought NBA 2k7 last week and I played it the first 2 nights I got it alot, maybe 3-4 hours a night. Then one night during a game it said it could not read the disk. I took it out and it looked like circular scratches on it. I took it back to EB and they just thought nothing of it and gave me another copy. Ive been playing gears and nothing has happened to that game but I am a little worried to start playing 2k7 again bc they only have a 7 day return policy and the dude at EB didnt even ask me for a reciept and he did not give me a new one.... Do you think it is safe to play?
