PS4 lets you access your game library on any console

Sony has revealed that players will be able to log into their accounts on any PlayStation 4 to access their game library.

The feature will allow players to download games onto other consoles and play them while they're downloading.

Team leader at Sony Europe's Research & Development department, Neil Brown, explained how it would all work at the Develop Conference earlier this week [via OPM].

"You can visit your friend's house, you can log into your account and play any game from your digital library, which is good," he said.

"But how useful is that if it takes half a day to download the game you want to play?

"With Play As You Download you get much quicker access to at least the first section of the game so you can start playing quicker. So this makes a digital library a practical option in the real world."

Playing while you download was featured in a PS4 trailer a few weeks ago, and you can watch it below.

The video shows a player buying Killzone: Shadow Fall, and choosing whether to download the single-player or multiplayer modes first.

You can then play the game after the first level is downloaded.

Brown also said that the feature works with game discs, too.

"This means that after the first few minutes your game can rely on having faster read speeds from the hard drive, which provides a better experience for players.

"This is a completely background process for the player. They don't have to wait for anything to install before playing the game. The game will launch as soon as the disk has been put in the drive."
