The ones I got lately looked like that - wonder if they are putting the disks in some sort of a cleaning apparatus.
I'm pretty sure the discs only look like that if the pad they are using is worn out and needs replacing. There's a 50/50 chance of the discs actually working 100% so be cautious with them. Unfortunately, places like GS don't switch out the pads often enough which causes shitty refurbs to be sent out everywhere. Hopefully, this was a quality control issue with Gamefly and they don't do what GS does.
