Na, das liest sich doch ganz ordentlich:
Everyone in your home can share digital games with each other. Your Xbox One can become your virtual game library filled with digital games that different people in the home bought. Anyone can pick any digital game on your Xbox One, sign in with their own gamertag and play – even if the owner is not signed in. Like physical media, you can also play many digitally downloaded games without being online, although experiences will be best when connected to the internet and Xbox Live. Finally, when you purchase a digital game, you can start playing even before the entire game downloads.
Because your digital games go with you, you can also use and share digital games when you sign in to another console. And, if you happen to buy a digital game when you are signed in on your friend’s console, your game will also be available on your Home Xbox One console for anyone to use.
