Playing games across multiple xboxes

I recommend setting up the xbox sharing by doing as the others have stated (switching your home account location), if your brother is will to do that. I love it because it allows my girlfriend and I not only to play games together but also share games.
Just be aware that you can only switch your home so many times in a year.

You need to setup up family share. If you make your console his home console then you can play his digital games .

Hi Fellow gamer,

Thanks for coming to the forums. You can set up the
home console of his account on your Xbox. Basically your brother will add his profile to your Xbox, set your Xbox as home. He then can remove his account if he likes. This will allow you to play the game on your console. Your brother will be able to play
the game on his console.

Thanks,

Brad

Yes this can be done through sharing the Xbox Home which will allow him to play any digitial games purchased and to share your gold whenever you have it.

If he were to set your console as his Home console you could access any of his games. https://support.xbox.com/en-US/games/game-setup/my-home-xbox
