Perhaps the biggest news post-console reveal here at Sony's E3 presser: the PS4 will play used games without any restrictions or authentication. In broader terms, that means that when you purchase physical media, that disc can then be traded-in at retailers like GameStop, lent / sold to friends or kept forever as part of your enduring library. What's more, unlike Microsoft's controversial Xbox One 24-hour offline gaming window, PS4 owners will not have to connect to the internet in order to continue playing games. Effectively, that makes the PS4 fully playable offline; it also arguably hands the E3 2013 crown to Sony. For a brief instructional (and intentionally cheeky) demo on how this used game process works, check out Sony's homemade video after the break.
