Maybe the game publishers should start including a netflix style envelope with their games. When you're done with the game, send the disc back for a $15-20 discount on a new title. The discount would need to be more than the gamestops are willing to pay to compensate for the lack of instant gratification you get from trading games in at gamestop and for the fact that you'd be limited to selecting a game from the publisher's catalog. However, I do think that the company would win in the long run by getting used copies of their games off the shelves.
