I don't know why this baffles people. Family Share serves as a replacement for physical sharing. It's really simple.
That's not what is baffling people. What's baffling people is that Family Share was about 100x better than physical sharing, far far more than a mere "replacement", so why would developers be ok with it when they weren't even ok with the original "Family Share" with 4 people that the PS3 had. And you did know that PS3 had a "Family Share" program right? The only difference is it didn't work with physical discs. It technically still does, just that it only works with 1 other person now.
Here's an example why it's WAY more than a replacement: My friend and I NEVER share physical games because we live over 100 miles apart. Sharing a game with him physically meant I would not be able to get it back from him if I had a sudden urge to play again. There was a good chance I wouldn't get the game back at all because I would forget what I had lent him. With the PS3, we shared freaking everything we bought on the PSN, even the 500 combined Rock Band songs we had.
What are these viable solutions then? If there are so many of them, write a blog post about them and you'll probably be offered a job within the week.
Sorry about the late response, but here:
Step 1: Choose your 10 people as your "family members" either directly from the Xbone or the PC.
Step 2: Buy your physical or digital game.
Step 3: Register your game to your account somehow. Any of these methods would work: specific code that could be entered directly on Xbone or through PC, popping disc into the console or even a PC with some software that MS could develop for PC, work with retailers on some sort of registration at point of purchase. (You might be asking why all these options? Because this would allow MS to still say that they don't require online on the Xbone.)
Step 4: Choose one of your friends to share the game with. Since they would have to download the game, the online connection is a necessity and at that point the system would tell said friend that he's been chosen to share _______ game. Friend then has 24 hours, 48 hours, or whatever set amount of time MS wants to set to play the game.
Step 5: Once the time limit is up, friend cannot play the game further until the original game owner uses one of the options in Step 3 to authorize that they still own the game. Original owner can still play the game regardless of whether or not he does this authorization.
There is one solution. Not the best I'm sure. I'm sure people smarter than me (and there are billions) can come up with something better.
I'm going to watch my phone for calls from the 425 area code now. When you said a week, did you mean a work week or a full week? Do MS headhunters work on weekends? Also does it have to be a blog post for them to see it? If so, I gotta go make a blog right now.
