When I was traveling this past weekend I stopped by a Gamestop to see if they had some games I was looking for. If anyone has been in a US GS lately you know they have those cheap game bins in the store, so I went & checked that out. Strangely, all of the games were Wii games. So after I looked around a bit more, I asked the girl working there if the cheap PS3 games were just on the wall with the others or what. She points to 2 boxes of disk-only games in envelopes at the counter and tells me that's them. I ask her if any of them have cases and she tells me no, they tossed them.
This is the only store I've seen so far that has tossed any PS3 cases, but I'm sure it won't be the last. I found 3 in the bin that I wanted & she said they *might* have the cases in the back, but they didn't. So I left them. I grudgingly accept cart-only DS games because I waited too long to start collecting for that system and it's virutally impossible for me to find complete games for it in my area. But for anything else, no case & manual = no buy.
