The PlayStation 4's Share Play feature, unveiled at the Sony conference earlier this week, is only available in 60 minute sessions, according to the company.
GameSpot reports confirmation from Sony that players will only be able to use the "virtual couch" system for one hour at a time. Share Play allows PlayStation 4 owners (with a PlayStation Plus subscription) to hand off control of a game to another player in an entirely different location, even if they don't own a copy of the game.
Share Play will arrive with PlayStation 4's Version 2 system software update this fall. "With this first-of-its-kind feature, you'll be able to play games with a friend just as if you were together in the same room," said Sony's Scott McCarthy, when introducing the gizmo.
