When you justify buying a new game at $60, knowing that you can resell it and maybe get half your money back makes it a little bit easier. Without that ability, the value of the game goes way down. Imagine if you were buying a new car, and knew there was no way to resell it ... Would that impact the price you were willing to pay?
