A customer walks into a reseller with a previously purchased game disc. This can only be done at retailers that, according to MCV, have "agreed to Microsoft's [terms and conditions] and more importantly integrated Microsoft's cloud-based Azure pre-owned system into its own." The game disc, having been registered in the system, now wipes the license use from the previous owner's account so that the installed game on their Xbox One can no longer be accessed.
Here's the delicate part: the publisher and Microsoft will now receive a cut from the sale. Previously, a company like GameStop pocketed 100 percent of the used game sale, now ConsoleDeals.co.uk is reporting it could be significantly less if Microsoft has oversight of the market. The pre-owned market would go on, but its glorious margins for retailers would be destroyed. Meanwhile, publishers would finally get what they've always dreamed of: a piece of that pie.
