Harrison: Okay, so, I can understand where some of the confusion may have come from, so let me try to help out there. First of all, you can buy a game on a disc from a retail store, come home and install it to your Xbox One. The disc contains all the bits and data on that game, which you can then give to your friend, and they can then install it on their Xbox One. No restriction on that, except that the second person obviously has to pay for it.
You can purchase a game in two ways: you can purchase it from a retail store or you can download it. So the act of putting the bits on the hard drive - the Xbox One doesn't really know or care what method the bits got into the machine, if it was from a disc or downloaded from Xbox Live. But obviously the users will then have to purchase that content.
What I think people are now confusing is the purchasing of content in the first instance with the ability to trade and resell the previously played games. We have a solution for that and we will be announcing exactly how that works in due course.
