my xbox series s

Yes I switched over to the series s and the games that were on my Xbox one arent on my series s

The Xbox one s or xbox series s?

There is no xbox S

And yes there is a difference

Xbox one s is just a xbox one s

A xbox series s is just xbox series s

Because on my Xbox series x, it only shows 'Optimized for series x/s' but if a xbox series x version of a game is NOT 'optimized' how would i know if I'm playing a series x/s version of a game?

There's no such thing as an Xbox One Series S. There's an Xbox One S and an Xbox Series S. That game is only available for the Series S/X, not the One. So if you have a One S, it will not work.

Hi there, my name is Gerardo and I'm an Xbox player like you. I'll be happy to help.

The only difference between a regular Xbox Series S console and an Xbox Series S Starter Bundle is that the Xbox Series S Starter Bundle includes also 3 months of Game Pass Ultimate, while the regular Xbox Series S does not.

For more information about the Xbox Series S Starter Bundle, please check the following link:

I hope this helps and if you have further questions please let me know.

Kind regards,
Gerardo.
