I think the two people playing the same game at the same time will be only for coop multiplayer, like 2 people could play halo 5 campaign on coop with only one person owning the game but for a single player game like ryze you won't be able to play at the same time as the owner. They said that feature would be up to the developers. Also I don't think you need to be online for one of your friend to access your game but if you didn't connect for 24h they won't be able to due to the check in feature.
The one thing I wonder about is will you have to download the game or does it stream from the cloud? because downloading 50GB games would take way to long

So, basically, you and up to 10 people (or is it yourself + 9 others) can basically share any game anyone in the group purchases. But, a restriction is put in place that none of the 10 people can ever play the same game twice if only copy of the game was purchased.

If there objective was to give publishers more money by eliminating used games, how is this any better? You basically took potentially 10 sales and made 1 out of it. Sure, they could also just lend the disc to the friends in the status quo, but in that scenario, one friend has to be "done" with the game. The family share means all 10 people, if played in an interleaved fashion, can all beat a game in less than a week. Seems weird and confusing.

Also, remember when the PS3 launched and you could "game share" with 4 other people. That's gone. I'm sure this will go the way of the dodo too.

Really? So that how Sony loyalists are playing it when they discover that the DRM feature of the Xbox One is actually offering an awesome sharing system?

What is so confusing about it...You can SHARE your games with up to 10 people, meaning all these people will be able to play your owned game at any time, the only restriction is that at any time, only one copy of the same game can be played by one of these familiy members.

This feature is just awesome and I do not what is so hard to understand.

lol okay, so now that they are offering something very good you are still bashing and even proclaming they are not learning from their lesson.
Keep going :)

I am not bashing...they are stepping back from the restrictive policy slightly. They are allowing flexability with the licensed titles. If you don't get that you'll never get it. The system is still intact, they are just saying "we'll give you this for whatever we restrict here". If I do buy an Xbone some years down the road I will definitely not buy any used games, because theres no point for me really. I probably wont even worry about the lending either since it will be the secondary console for sure. Disc based > Digital when it comes to buyer power.

What did you miss about my reply? What about the "Haven't really learned their lesson, they just dont want to tear down the infrastructure."... Read my comment again, this is what I'm talking about...

Also, allowing to share games with 10 people is way more than stepping back "slightly"!

For MS this kind of is a slight step back. If you have read the recent reports they are still very strong on their digital future front. That is changing nothing major about the deal but rather tweaking it somewhat. 

i love these twitter threads we are getting,cloud sharing should be pretty useful

Be aware imagine, that the 10 family members thing is not simultaneous, the friends have to be on your list for more than thirty days and they cannot all borrow your games at one time. It's first come first served then relinquish your rights type situation. As i said its a slight step back from the hell they've brought, it isn't fixing the problem completely but sugar coating the wound.

Well that's your oppinion. I'm pretty sure a lot of people are very happy about that. Including myself who have kids. Not having to use a disc and being able to have my kids to play my games on their own devices is just BIG.

As far as Microsoft and their thought about the digital front; you are talking about it like it is something evil. Again, your oppinion; I think it is the future.
So if you think it is a slight change just because you want them to move away from the digital distribution; well too bad for you; but you look it front another point of view; and are actually looking forward for the digital aera; this sharing system is huge...
