I keep reading MS 'statement' and it seems to be pretty clear that you will be able to have yourself AND a family member play the same game..
That reads quite clearly, "you can ALWAYS play YOUR GAMES" that implies whether they are on the 'shared list' or not,
"and any one of your family members can be playing from your shared library at a given time." is quite unambiguous.. That's 2 people playing a game at the same time.. no doubt covering the scenario I have where I share games with my 7 year old on a second console in the house..
Of course, you may be right, but it certainly seems clear enough to me.. and you can't have 2 people playing a physical disk at the same time, and of course the logistics of distributing that disk are not so straight forward either.
It's pants we can't just lend a disk, although Steam says FU on that one even more, but I'm not totally over reacting at the moment.. I can see where they are heading and it's diminishing my impetus to buy an XB1 despite usually owning all major consoles and enjoying all exclusives..
Also, the other implication of MS' statement is for a family member to play one of your shared games around a friends house..
"Just like today, a family member can play your copy of Forza Motorsport at a friends house".. you don't have to risk your disk being scratched/lost and as the owner, you can still play it yourself..
I do think 'family' will be very restricted and who wouldn't want to stick with offline disk swapping as we have today, but you have to approach this rationally.
