One thing I think will happen is that you can't change your "family" group. Otherwise you'll get gamesharing among large numbers of people for a single game as people link and de-link family members all over the place.

Also pain in the arse for any MP heavy games like Halo / CoD / BF. If only you and one other can play at any one time it means all your other family group needs their own copies of the game in order for all of you to play online together. So it's main benefit is for offline SP play.

I wonder too if achievements might be locked only to the owner of the game.

It seems very incongrous for disc swapping to be only to a person who's been a friend for 30 days, and it can only happen once for any given disc, but family group sharing among 10 people be soo free and open and by the way things look very easily abused to hurt new game sales much worse than used games.

@Goddbless: DRM doesn't have any real benefits for consumers. Family sharing is the circumvention of DRM, i.e. it's the opposite of DRM.

As a Sony fan I just want to help my Xbox fan bretheren to not fall for this apparent benefit until the full details and limitations are known. There's no free lunch, as they say, and this family group thing has all the appearances of a great big free lunch. Which 95% means it's not going to be as good as it seems right now. I'm just recommending a bit of healthy scepticism on all y'all's part so that you will avoid both over-hyping this thing and being disappointed when the full reality of the situation is revealed.

I also think you won't be able to change your family group members. Maybe once a year...maybe never, It would be chaos if you change them as you please.

I see no over hyping, all I see is Sony fans downplaying the feature and making up limitations and decrying it as impossible simply because it's a great feature for gamers.  People are reacting to Sony fans saying this isn't possible, if you all stop saying it's not possible then the discussion can move on.  It's not the Microsoft fans that need to be more reasonable, this is after all their area of the forum to discuss their console.

Sony has been previously brought up into this thread/discussion far before I mentioned them. 

And the existence of the feature isn't speculation, obviously, but the fine details are pure speculation! Not a single person in this thread right now knows how this clearly works, we don't know the fine details, if we did, we wouldn't all be arguing about it right now, would we? As I stated in my previous argument, this is far too good to be true as it stands for a variety of reasons, there will be a catch in some way or form. Also I find it funny that you avoided responding to the key premises/conclusion of my argument, classic lol. 

You miss the point, we don't know actually know any of the fine details of how this works... It's not Sony fans are saying this is "Impossible", we're simply saying it's more than likely going to be more restricted than you think, instead of how open all the Xbox fans are claiming this is going to be. Such a conclusion can literally be found from basic reasoning skills...

Also, yes, people are hyping this to no end, especially the XBOX fans it seems. There are people left and right stating it's going to be this crazy awesome beneficial feature and people can just share openly to 10 people and the only restriction will be that one person can play at a time! No way in hell is it going to be that open, and even if it is, you DON'T KNOW right now. Everything is pure speculation at this point because none of us know how the feature really works, none of us know the fine details, and as I stated previously in the thread, if it seems too good to be true it probably is, because the devil is in the details my friend.

Oh Gods, lets not start suggesting forum segregation. This is not an area only for MS fans to talk about MS stuff. This is the area of the forum for ANYONE to talk about MS stuff, good, bad or indifferent, praise or criticism, right or wrong.

I guess we'll see whether "a great feature for gamers" is over hyping or not once the Xbone releases and Xbone owners start to use this feature. Count me as one who is very sceptical about how this thing will play out, simply for the reason that, as badgenome has already pointed out, 3rd parties forced Sony to cut the 5 activated platforms down to 2 for PSN games. If the sharing thing is exactly as you guys think then expect 10 to be cut back substantially.

And there you go again, its rather sad to fly in the face of all the evidence and statements that have been OFFICIALLY given.  I understand this will be devastating to all your arguments about how anti consumer the XBO is but please try and at least debate the facts we have to hand now rather than making stuff up.

It's already been shoved down our throats that Microsoft themselves have told publishers that this is the DRM model they are going to use so I doubt they have that much power to stop anything and it's quite clear Microsoft have showed them how they can make more profit with this model.  This is a great feature to engage more gamers to try software they wouldn't normally get the chance to play, I would imagine the publishers realize it is a great market to entice more potential customers to future products.

If people cant even accept that the XBO might have a single positive feature then perhaps we should look at segregation.  It is literally impossible to have any positive discussion about the XBO on this forum and nothing is done about those trolling.  So far since E3 it's been inferred I'm an idiot/fanboy for liking the XBO, I don't give a shit about consumer rights, I'm in denial, etc, etc.  NOT one poster has been banned for making these statements, its a joke.

its a great idea funny how some still look for negatives

I think this is really huge if confirmed it is true. Let me make one example to compare: Ballmer and Kaz are good friends.

1. Both of them only have PS4, so:

1.1. If Ballmer borrow a disk-based game from Kaz, then Ballmer can play the game, but Kaz cannot because he doesn't have the disk;

1.2. If both of them want to play a same game for multi-player at the same time, both of them need to buy the game from retailers or from PSN;

2. Both of them only have XBOX ONE, so,

2.1. If Kaz is one of Ballmer's family member, then he will have the access Ballmer's games and play them. It is equal to Ballmer lends the games to Kaz;

2.2. If both of them wants to play multi-player at the same time, both of them can play even Kaz doesn't need to purchase the game.

So who has the advantages?

If that's what can be done, then that's pretty cool. His statement however, suggests that only one person can be playing the game at a time.
