- Now that you can pre-order PlayStation 4 titles such as Knack
on Sony's PSN Store, they have adapted a new PS4 digital DRM (Digital Rights Management) policy as detailed below.
To quote: "With the PlayStation Store, you can download your games to two systems. However, playing those games is a different story. When you're on your primary system, the one you use all the time, you can play as you normally would.
But to play on another system, the owner of the game must be signed into his or her PSN account. So for instance if I go to a friend's house and want to play Knack, I need to stay signed into my PSN account in order for us to continue playing. If I am on my PS4, I can play it without signing in.
This is different from the current digital DRM practice with the PS3 where you can download on up to two systems, but don't need to be signed in with the purchasing account to play said game.
The PlayStation 4 will be available in the US on November 15th and Europe on November 29th."
