Third party publishers will have the choice to introduce DRM on second-hand PS4 games, just as they can on Xbox One, according to SCEA boss Jack Tretton.CVG reports that in a GTTV interview, Tretton stated: “The DRM decision for third-party games will be up to publishers.” Tretton did, however, reinterate that firstparty titles would not be subject to DRM.“When a gamer buys a PS4 disc, they can trade in, sell it to a friend, or lend it, keep it forever,” he added. “PlayStation 4 disc games don’t need to be connected online to be play, or any type of authentication. PS4 won’t require you to check in.”We have contacted Sony for clarification.Update: Sony has issued a statement on the matter to GameInformer:The Online Pass program for PlayStation first-party games will not continue on PlayStation 4. Similar to PS3, we will not dictate the online used game strategy (the ability to play used games online) of its publishing partners. As announced last night, PS4 will not have any gating restrictions for used disc-based games. When a gamer buys a PS4 disc they have right to use that copy of the game, so they can trade-in the game at retail, sell it to another person, lend it to a friend, or keep it forever.
