Sony: Fear not, the PlayStation 4 will play used games
It's official: there is no need to worry about a patent that stops consoles from playing second-hand games -- it isn't intended for Sony's next console.
For anyone who was concerned about Sony's patent that would tie games to consoles, stop your fretting. Your PlayStation 4 will not contain that technology.
Speaking to Eurogamer, Sony Worldwide Studios boss Shuhei Yoshida attempted to lay to rest any concerns that the just-announced console would prevent people from playing second-hand games. Discussing the idea of restricting the play of used games, Yoshida touched upon the expectation of customers: that once you have bought a physical disc, you should be able to use it how and where you will.
