Xbox One: Play All Your Games Through the Cloud, On Any XB1
Microsoft has confirmed that you’ll be able to play any and all of the games you own through the cloud, on any Xbox One, as long as you sign into your account.
The company revealed that one of the few things its cloud service will be good for is that you’ll beable to access your entire library without needing to install the game from a disc. All you have to do is download the game after signing into your account, and you’ll be able to play it straight away.
Here’s Microsoft on the matter:
Access your entire games library from any Xbox One—no discs required: After signing in and installing, you can play any of your games from any Xbox One because a digital copy of your game is stored on your console and in the cloud. So, for example, while you are logged in at your friend’s house, you can play your games.
The only other good news about the Xbox One might be the fact that you can buy all new games at launch as digital downloads without ever having to get off the couch. Read about that here.
