Microsoft is working on a new system called Positron that could let Xbox players turn their physical game discs into digital copies.
The idea is simple: you put the disc in your console or drive, the system checks that you own the game, and then it adds a digital version to your Xbox account.
Once converted, the game would work with cloud gaming, play on many devices, and fit better with new hardware, while the physical disc would likely stop working afterward to stop people from sharing or selling the same copy.
We do not know which games would work, if it costs money, or when it might launch, and Microsoft has not confirmed it, so this is still just a rumor.
