Buying a Series X enhanced game to play on game-sharing xbox one

HI,

This an Xbox One X enhanced game. But to get the enhancement you'll need either a Xbox One X or either one of the newer Series X|S machines. The Series S is a digital only console though.

On an original Xbox One or One S, it will be the BC 360 game with no enhanced graphics.

You'll get access to an enhanced version regardless of disc or digital, but you need the right console to be able play the enhanced version.

This is an incorrect assumption. You can insert an xbox one disc and download updates that may improve visuals and frame rates on Xbox Series X/S but in order to play you still need the disc unless you own the digital version of it.

Xbox Series X will utilize the Xbox One X version of enhancements while Xbox series S will use the Xbox One S enhancements.

You will not get a free game by borrowing or renting a physical version of a game and installing it on Xbox Series X/S.

You would have to buy the standard edition in order to play it on both the One and the Series X.

Microsoft introduces "Smart Delivery" with the Xbox Series X, which means, that if you own an existing game (like Minecraft in your example, or Gears 5) or a new game comes out for Xbox One and Xbox Series X with improved graphics on Series X, you won't
have to buy the game twice.

With Smart Delivery you will play the "enhanced" version on Series X, and the "normal" version on Xbox One.

I would presume that if a game is Xbox One X Enhanced, those benefits will also appear when the game is played on Xbox Series X, along with any Optimized for Xbox Series X benefits that same game might receive through future updates. I doubt seriously it
would be a step backward when played on the superior hardware.

Keep in mind the Smart Delivery feature, which will enable Xbox Live to send the best possible version of the game to Xbox Series X automatically. So that may be the Xbox One X Enhanced version, or (if the developer makes such an update possible) the Optimized
for Xbox Series X version. Given the choice, I'd want the Optimized version.
