The Xbox One (and the PS4 I think, although I don&#x27;t own one so I&#x27;m not sure) doesn&#x27;t let you play a game off its disc - you have to install it. The only functional differences between disc games and downloads is that you can sell&#x2F;loan&#x2F;trade&#x2F;gift disc games via the physical media, and consequently the disc has to be inserted while playing as proof of continued ownership.
