I just gotta fucking MARVEL at the weasel words used in the initial MS memo about famliy sharing:
"Give your family access to your entire games library anytime, anywhere: Xbox One will enable new forms of access for families. Up to ten members of your family can log in and play from your shared games library on any Xbox One. Just like today, a family member can play your copy of Forza Motorsport at a friend’s house. Only now, they will see not just Forza, but all of your shared games. You can always play your games, and any one of your family members can be playing from your shared library at a given time."
The devil is in the details. "playing from a shared library" is not the same as "paying your shared games" or jet "playing your games" because those last two imply playing the whole game. Saying "playing from the shared library" is more vague and does not directly state that the other person is playing the exact games in the library. they can be playing time limited demos from a range of titles
from the shared library
They also use the phrase "new forms of access" when referring to the access you provide to your shared library. Yeah, the access is now a 60 minute demo as the game streams in. Not the typical kind of access we would expect.
It's one of those things that, in retrospect, is so goddamn misleading and purposefully confusing that it's just fucking
beautiful. I grudgingly respect Microsoft's copy writers for wording the plan the way they did.
edit: even the bit when they say "...play
your copy of Forza". Yes, they can play
your copy of Forza (direct language, there). How does MS determine what is your copy of a game and not a shared copy? If it's tied to your account so that implies that your account is logged in on that other machine. there's so many little escape clauses in there.
