Sony has announced that its upcoming PlayStation 4 console will not impose restrictions on used games, nor will it require an online connection. Speaking at the company's E3 keynote, SCEA president and CEO Jack Tretton took pointed swipes at rival Microsoft, which will require Xbox One users to connect to the internet once every 24 hours, and is allowing publishers to block access to used games.

"PlayStation 4 won't impose any new restrictions on used games. This is a good thing," said Tretton, to huge applause from the audience in attendance. "When a gamer buys a PS4 disc, they have the rights to that copy of the game." Tretton added that disc-based games "won't stop working if you haven't authenticated within 24 hours."
