E3 2013: Wave of cheers as Sony supports used games on PS4

Console giant will not restrict pre-owned market in any way, says Tretton

A wave of cheers echoed around the E3 conference room as Sony announced it would not be blocking pre-owned games in anyway on the PS4.

In what appeared to be a direct response to the controversies surrounding Microsoft’s Xbox One, SCEA president Jack Tretton said there would be absolutely no restrictions on used games.
This means that consumers will be able to sell on games they have bought, and also loan them to friends.
And in an effort to ease minds over potential always-on requirements, he also said that a PS4 does not need to be connected online for users to play their games, and there will be no authentication codes either.
