GTA on both XBOX One as well as XBOX360 using the same account

Hey there Arnogro.

You'll need to purchase a separate copy of GTA V for your Xbox One as it isn't available via Backward Compatibility.

You can use the account on both your xbox one and xbox360 at the same time.

Hello, my brother and I play offline with one xbox360 console and 2 remotes in same game with 2-player mode. Our dad purchased one xbox 360 gold live account which we play by taking turns. Our dad wants to know if by buying a second xbox360 gold live account
we can both play at the same time using the same xbox360 console on two seperate xbox gold live accounts on two remotes in same game. Can someone please confirm if this is possible or do we have to buy a second xbox 360 console?

If you have the game digitally already, you may well have the Xbox 360 version. For more details: https://www.engadget.com/2018-05-31-gta-san-andreas-xbox-one-backwards-compatibility.html

Be sure you're using the same Microsoft account that owns the digital version of GTA SA on your Xbox One, too.

I got Rare Replay to and have a Xbox360 as well. Rare Replay install all Xbox360 and XBL-Arcade games separatly on the xbox one, you can start these games directly from your library.

It behaves like a purchased game from the store, usually the compatible Xbox360 games are also still playable on the old xbox360 with the same account.

But not with the Xbox360 and XBL Games from Rare Replay, these licenses are not transferred as usual for the Xbox360.
