The stage lights had barely dimmed at the Xbox One event before the internet started tripping over itself with questions about how the second-hand market was expected to operate -- or if there was going to be one at all. Microsoft assured us there would be, but aside from whispers of a used game "activation fee" the finer details were kept under wraps. We may know a little more now, however, as MCV claims to have heard specifics from retailers who have been briefed by Redmond on the trade-in process. Allegedly, shops that wish to buy and sell a title will need to be hooked up to a Microsoft database so that access to the game can be removed from the previous owner's account and transferred to a new one. A retailer can sell the game for whatever it likes, but the system will ensure that a cut goes to publisher as well as Microsoft. It all sounds fairly logical, but who knows? The truth could be even more complicated.
