We would like to clear up a misconception that has been spreading the web today. It is being reported by various news sites that Sony has told retailers it will be illegal to sell second hand games, because consumers only buy a license to play the game, not to own it. We would like to confirm that this is untrue. Yes, Sony does have a patent to do this (sort of, see below), but they have already come out and confirmed that PS3 games will be playable on any PS3 console. In fact, these rumours were actually spread back in November last year. The issue was that Sony would create a dynamic DRM system so that each PS3 game would only play on one physical console (the first one you put it in). This would obviously mean rentals and reselling would no longer me possible. It was then that Sony made a statement: "This is false speculation and that PlayStation 3 software will not be copy protected to a single machine but will be playable on any PlayStation 3 console
