Most people who trade in games go spend that money on a newer but still second-hand game, netting the publishers/producers all of $0. Or so has been my experience, anyways. And the music industry absolutely complains about second-hand shops. They just know there's not a damn thing they can do about it. Truth be told, I think many would prefer to have their content downloaded than resold second-hand. For all they're concerned, it might as well be a pirated Chinese knock-off copy, since it's a copy of their product that's actually being *sold* and they're not getting anything from it. I can't speak for the industry, but I'd rather nobody get paid than someone who's not me get paid when content I produced is acquired.
