How to play game bought on a different profile on the same console?

Your brother would need to set the console as his Home console in order to share it with you.

Hey there Rocker! Are you playing this game on the same console you originally bought it? This type of thing usually happens when you're playing on a different console from the one it was originally bought on.

This is just because when you download a game, ownership of that game is given to the console that originally purchased it and the profile that it was purchased from. So if you play on your profile on a different console, you are able to play while signed onto
Xbox LIVE, but you cannot play while offline.

If you are trying to do it on the same profile, then that is not possible. Profiles on Xbox One & Series X|S can only play games on one console at a time.

If you are trying to let someone else play your Game Pass games on a different console at the same time as you, then you need to make the console that you want to share the games on the Home Xbox using the account that has Game Pass, then anyone with a different profile can play those games at the same time as you.

Bear in mind the Home Xbox setting is only meant to be used in the same household, as using it with someone else not in your household can result in a suspension or ban.

ok thank you, that helps a lot

Looking on the back of the game box shows the variations in the way the game can be played,

ie, single player, players 1-4, system link, on-line multi-player, etc.

When it shows that a game can be played by more than one player then that is usually a split screen option were upto four profiles can play the same at the same time.
