Piracy is illegal in many countries because (as far as I can make out) people pirating games are not giving the company who made said game money for using their product. Buying/Selling second-hand games is legal in most, if not all, these countries. Why? Is it not the exact same outcome as pirating games? The purchaser of a second-hand game now owns that game and has not given the company who made it any money for their product. This seems like another double standard to me, and one I feel either makes piracy morally fine or buying/selling second-hand games morally wrong, depending on which side of the fence you fall on.
