Buying Xbox series s and will it retrieve own games from original Xbox

Yes. Anything you own digitally is tied to your account, so you can just redownload them. As long as you've veen online when playing, your saves are stored on the cloud and will sync up when you play.

Hi,

The last and final set of BC games were released as part of the Xbox 20th anniversary, there won't be any more Xbox 360 or original games for the Xbox One/Series X|S.

Also, the Tenchu series of games is not owned by Activision. Activision sold the rights to the series to another developer, From Software in 2004.

Hi, JoeMcShane1!

You cannot transfer purchased game discs to the Xbox Series S. If you own an Xbox Series S and want to play games that you own on disc, you'll need to purchase them again from the Microsoft Store. If you plan on playing disc games, you may want to get the Xbox Series X instead of the Xbox Series S, as it has a drive.

Hi,

While you transfer any game installed from an Xbox One to a Series S, disc based only games won't work unless you also own the digital license.

I take it you don't own the digital license? If not then you would need to buy the game again from the Xbox Store.

Hi,

A common problem when running newer games on such older hardware like the original Xbox One and Xbox One S. The Xbox One lacks the processing and graphics power of the Series X and S consoles. I'm afraid there isn't anything you can do to improve things
on your Xbox One. You'll need a Series X or S to get a better visual experience.

Luckily if or when you buy a Series X or S, your game will be updated to the Series version for free.
