Can you play saved game from Xbox one version on series x/s version of same game??

It's important to know which game your friend bought.

I say this because there are currently three versions of the Series X/S game. Gta 5 Online, Gta 5 Series X/S and Grand Theft Auto V (Xbox One and Xbox Series X|S).

If he has purchased Grand Theft Auto V (Xbox One and Xbox Series X|S), which gives access to the game for Xbox One and Xbox Series S/X, he can play online with you as long as he downloads the Xbox One version, so you and he will have the same save and can play online.

If he is a Game Pass Ultimate subscriber he can download the game in the Xbox One version and play with you.

They are two versions of the game available, the Xbox One version and the Xbox Series X|S version. Make sure you have purchased the same version you have been playing, and the save should continue from where you left off.

Hello Tameaka.
My name is Ezequiel. I'm an Independent Consultant and I'm happy to help you today. Great question, in the store you will find three versions of Hogwarts Legacy, one for Xbox One, another for Series S/X, and the Deluxe version, the Xbox one version you can play on any console in the Xbox One family, the Series S/ X only works on new generation consoles, and the Deluxe version comes with both Hogwarts for Xbox and Hogwarts for Series S/X game versions and exclusive content. Be very careful when making your purchase not to buy the Series S/X version of the game, this version is only compatible with the latest generation consoles. The version of the game Hogwarts for Xbox One can be played on Series S and Series X consoles, but you won't have the same graphics as the exclusive version for Series S and Series X consoles. If you have any questions, please contact me again and I'll be here to explain any other questions.

The One version of the game can be played on a Series S/X. The Series S/X version cannot be played on a One.

All Xbox One games can be played on the Series S/X via backwards compatibility. Kind of like how you can play 360 games on the One now. You would be playing the One version of the games.

With Cross Gen Editions/Smart Delivery, you're buying the One version and get an upgrade to the Series S/X version of the game when you get the new console instead of having to buy the Series S/X version and you an take advantage of some of the upgraded
features.
