PlayGo "Makes A Digital Library A Practical Option"
Sony has confirmed that PSN accounts and digital game libraries can be accessed into on any PS4 console with an internet collection, using the new PlayGo service to quickly snag specific components of a game to get into the action as quickly as possible while the rest of the title downloads in the background.
“You can visit your friends house you can log into your account and play any game from your digital library, which is good, "Sony R&D senior team leader Neil Brown told OPM at the Develop conference. "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.
“A similar system also works on Blu-ray, chunks are automatically copied to the hard drive in the background. 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, and 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.”
