We need some old games on Xbox Series X

Not going to happen.The Xbox One is an old console now & more & more devs are just releasing games for the Series X/S & not bothering with the Xbox One anymore.

If you want to play the newer games then you'll need a Series X/S at some point.

I hope all the old Need for Speed games came to backward compatibility but we have to wait until after the Series X comes out.

Keep in mind you need a series x or s to play ir

Xbox one's arent compatible since they are over 10 years old and this include xbox one x

When xbox one games are made thwy just say xbox one not s or x

However for next gen games it's series s or x or both for digital releases only

Hope you're doing great today despite this GUNDOWNZERO

I understand that you want to play disc games on the series S but I think you already know that's not possible..
Series S is an all digital console. A Disc can't be be used on it.
I know what it feels I have some physical copies for old games like FH3, and basically all the forza saga.
I can play the games only on my Series X.

Both consoles are great, but depending what you need you may need to choose between Series S and X

If you have old games and you don't want to buy a Series X your best bet right now to play them is get an Xbox One X or Xbox one S console

That the Xbox Series X supports HDMI 2.1 doesn't mean your TV needs to support that too. You can user your old TV with the Series X for sure.
