I still don't get how it matters. If the publishers have a problem with it they should do something about it. I don't blame GS/EB for it.
For me, I LOVE buying used as I have 7 days to return it for a full refund.
Game companies/Publishers have no problem releasing trash games a lot and when buying new I'm stuck with it and they got my hard earned money for a crap game.
If the publishers want to guarantee all thier games will be quality and not be turds in a box then ok...That won't happen anytime soon.
I do however totally agree about their labor policies and I've voiced that with more than a few district managers mainly due to having some friends that work there.......
