It'll depend on the publishers setup for that game.

What i want to know is how much we get for a used game sell and how much they will cost, because what the rumors say is that we get 1 or 2 dollars/euros for a sold game and the retailer gets a 5 euro cut and the rest is going to the publisher. I still think they are hiding pertinent information and i am 100% sure that this is a trap.
Want to lend games to your friends? No dice.
You can sell your new game once for an undisclosed ammount that is probably not gonna be worth it. If you buy a used game, you cant resell it, it virtually becomes trash.
Most important of all, publishers are beeing given the choice to apropriate themselves of revenue that isnt theirs by right. I call that theft.

At least your whole family doesnt have to buy the same game anymore.

Still, not buying this in a million years.

What I don't understand is this family sharing thing, does my entire family have to be using the same gamertag for it to work?

Sealed the deal, already have a Wii U and will be picking up only the PS4. As a GameFly member and someone who borrows out and borrows games from friends and coworkers this isn't going to work for me, plus I refuse to pay for or purchase a console that requires me to check in with them when and where I play. I travel quite a bit and take my console of choice with me.

Nice knowing you MS. My dollars will go to Japan.

And indirectly, Steam is the reason for this shit.

If you are without power for longer than 24 hours and can't log back in, you can't play your games. 

Anyways, this console isn't for me. For me I would need the ability to privately sell my disc based games. If not, then their games better be real cheap. No $50 and $60 games. I might be reluctant to buy @ $40. At that point it would really depend on what trade in values are at retailers.

No you  are right. If power goes out for a couple of days, and you start up your Xbone after that(once you get power back), you need to log in online first to be able to play your games.

Hats off everyone for a fellow brother who is taking a ban like a man to speak the truth.

I don't endorse calling another member an idiot but everything else I 100% agree with.

Realy  who plays 24 hours straight of games these days?  Thats very reasonable. Imean if anyoen plays 24 horus straight of games then that person should be getting a life . Not  trollign but being serious here. There are signifcant health risk by doing that as thats alot of hours of gaming. All you need ot do after playing is to put the game back in and you are on again for the next 24 hours. HOw hard is that?  SHouldn't even take you 1 min to verfy it. This reminds me of teh blu ray vs dvd situation where ps3 suers complained that its good to ue blu ray because you don't have ot get up and change disc  when changing dvd disc would end being fraster tehn waiting for the blu ray game to load. The rules stated by MS ios actually faire then what i expected. I thought it was going to be alot harsher then that.  People complaining  are cheapskates  and want everythign for free.

Are you hoping to borrow ... for example - EA games on the PS4?
