InSaintMonoxide: The good news are that the physical games come on Blu Ray discs for PS3, which means they are not going to be too difficult to find in good condition as Blu Rays don't scratch.
Don't know where you got that notion, as they do indeed scratch. They may be a bit harder than a DVD to scratch, but they still do. And I know that for a fact, as my PS3 screwed my favorite concert blu-ray on insert ... we presume there must have been some dirt (even though I had just dusted the damn PS3) on the slot brushes. Not been brave enough to use any treasured discs in the PS3 since. In fact, if it don't have a drawer (tray) from now on I am not buying it, too damn risky and I always knew it was gonna lead to grief one day, and of course it had to be that disc didn't it ... lucky I'd backed it up to ISO, but that's beside the point, and it wasn't a cheap buy either, still isn't ... grumble grumble. I'd just bought a stand-alone blu-ray player too, but hadn't yet set it up with my system, and I was showing the concert off to a mate visiting from interstate ... or rather, tried to show it ... played some of the ISO before he had to leave ... ran out of time ... grrrrrr.
Anyway, I have seen plenty of scratched blu-rays, though I keep mine sealed and in pristine condition when not in a player. Before rental stores died, you could find plenty of blu-rays with scratches ... some people are selfish shits.
By the way, blu-rays need to be harder and more durable, because the readers have to be that much more perfect.
