Installing a used game on your Xbox One will not require a fee, says Microsoft corporate vice president Phil Harrison. At least, not exactly.
Speaking with Kotaku, Harrison expounded on data already gleaned from Official Xbox Magazine, that Xbox One games must be registered with a single-use code tied to the player's account. To install the game data on another Xbox One, the owner of the new machine pays the game's list price on Xbox Live.
"The bits that are on that disc, you can give it to your friend and they can install it on an Xbox One," says Harrison. "They would then have to purchase the right to play that game through Xbox Live."
With the physical game discs essentially worthless without an activation code, this may have profound implications on the used games market.
Harrison also hinted at an additional feature to be explored later, which would allow players to trade and sell their games -- or rather, the right to play them -- through Xbox Live. Details on that will presumably arrive close to or during E3 in a matter of weeks.
UPDATED: Larry "Major Nelson" Hryb has commented on the issue of used games with the following:
We know there is some confusion around used games on Xbox One and wanted to provide a bit of clarification on exactly what we've confirmed today. While there have been many potential scenarios discussed, today we have only confirmed that we designed Xbox One to enable our customers to trade in and resell games at retail.
Beyond that, we have not confirmed any specific scenarios.
Another piece of clarification around playing games at a friend's house – should you choose to play your game at your friend's house, there is no fee to play that game while you are signed in to your profile.
