Microsoft's Phil Harrison has once again tried to clarify issues surrounding the game sharing aspect of Xbox One, although there is still some slight confusion.
"So, think about how you use a disc that you own of an Xbox 360 game," he said to Eurogamer. "If I buy the disc from a store, I use that disc in my machine, I can give that disc to my son and he can play it on his 360 in his room. We both can't play at the same time, but the disc is the key to playing. I can go round to your house and give you that disc and you can play on that game as well.
"What we're doing with the digital permissions that we have for Xbox One is no different to that. If I am playing on that disc, which is installed to the hard drive on my Xbox One, everybody in my household who has permission to use my Xbox One can use that piece of content. [So] I can give that piece of content to my son and he can play it on the same system."
Harrison then talked about what happens when you go around to a friends house with your game.
"I can come to your house and I can put the disc into your machine and I can sign in as me and we can play the game," he explained.
"The bits are on your hard drive. At the end of the play session, when I take my disc home - or even if I leave it with you - if you want to continue to play that game [on your profile] then you have to pay for it. The bits are already on your hard drive, so it's just a question of going to our [online] store and buying the game, and then it's instantly available to play.
"The bits that are on the disc, I can give to anybody else, but if we both want to play it at the same time, we both have to own it. That's no different to how discs operate today."
Harrison also made a brief comment about how you'll be able to trade previously paid games, although an announcement regarding this in due course.
"We will have a system where you can take that digital content and trade a previously played game at a retail store," Harrison said, before reiterating that they are "not announcing the details of that today, but we will have announced in due course."
We aren't sure how this will work if say, you have two consoles in the same household. Will you still be able to share games without a fee? This much is unclear as above Harrison says you'll be able to share games on the "same system."
There are certainly plenty of questions. Hopefully E3 will bring the answers.
