Disc and gamepass

most of the time no, but the digital licence will supercede the disc version.

if you downloaded a game in gamepass for example then buy the disc version, there would be no point using the disc while that game is in gamepass, if it leaves gamepass then just pop in the disc and it should work fine (should but this is Microsoft lol).

All games are installed to HDD (Internal or external USB) and are run from there regardless if they were purchased on disc or digital. Any games that you previously purchased on disc which are now included in GamePass no longer need the disc inserted to
confirm your purchase license as long as the title remains in GamePass as the system knows you are entitled to play it based on your GamePass subscription.

It remains to be seen what happens when a previously purchased disc title is removed from GamePass. Some of my disc titles fall into this category of having been added to GamePass however I can't comment about that leaving GamePass experience until it happens.

I did that with Minecraft. If you try to launch it without the disc, it will say yoou need to renew Gamepass. Or If you tried to boot the game on disc and it asks you to renew Gamepass, then check the disc and try again.

I had a similiar experience a few weeks back.

All my disc games that is also available on Gamepass seemed to not need the disc in the drive to be able to play. Since my gamepass subscription expired i had to place the disc in the drive to be able to play the game.

if you have ultimate then that licence from gamepass with override your disc licence or digital owned licence whilst the game is either is gamepass or you unsubscribe.

you still own the game but it will show like this until one of the above changes. also means you don't need the disc in to play if it's in gamepass.
