I took my copy of GTA IV back after it gave me a disk-read error twice. I had the receipt and they gave me a new copy. I love GTA IV so much I'll just keep it if my other copy is on the fritz.
The only other game that happened to me was Mass Effect. I just flipped that damaged copy on eBay.
It could be the 360 and when I make my move and get set up, I'll buy a newer 360 anyhow and just keep this one in my living room.
