Xbox One game version instead of Series S/X

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.

They released that game as a One version and as a Series S/X version. The Series S/X version will only work on a Series S/X.

The Series S/X version will only work on the Xbox Series S/X, not the Xbox One. You would need the Xbox One version of the game.

It's very easy how to check which version of the game you bought. Check the game case. If it says, Xbox One & Xbox Series X|S, then you have the Xbox One version of the game. If it just says Xbox Series X|S, then you have the Xbox Series X|S version.

NO! Unlike some games that have an Xbox One version that will upgrade to the the S|X version if you put it in a series X, NBA2K for S|X is a complete different version than the Xbox One version and it will not work if you put the disc inside of an Xbox One. Xbox One cannon run a Series X game and putting a Series X disc inside an X1 will not install the X1 version.
