According to Neil Brown, R&D Senior Team Leader at SCEE, revealed during the Develop Event in London that digital games on the PS4 will work pretty similar like the PS3 where you can access your game library, though with the PS4, you can play as it downloads. Since PS4 games are expected to exceed 8GB, one of the things that will really benefit gamers is that they don’t need to wait for the game to completely be downloaded onto the hard drive. The moment the game starts downloading the data, it will be playable right away!
You can visit your friend’s house, you can log into your account and play any game from your digital library, which is good. 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.
In addition to the good news, Neil also talked about how the installs will work when a game requires one:
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.
As someone like myself who gets annoyed on the long game install on certain games, I’m glad Sony found a solution to it.
