will Xbox One game icons ever have a side-strip like Xbox and Xbox 360 titles do, on Series...

I think the Xbox series x is perfectly capable of running every Xbox game ever made since it's a powerful console.

Hi

To run 'every Xbox game ever made' would require a full software emulator, this likely doesn't exist and to make one is no small feat. Xbox One achieves BC by the BC team taking each individual game and reverse engineering and repackaging title by title. These games then had to be fully tested for performance and bugs which is very, very time consuming.

The Series X|S achieves BC with Xbox One games in a totally different way. The Series X|S consoles are very similar architecturally to the Xbox One, with massively more powerful processing and graphics hardware. This is why almost all Xbox One games run on the X|S.

I seriously doubt we'll see any more Xbox 360 and original titles. More than likely the event may focus more on FPS boost for Xbox One games running on Series hardware.

They are not bringing Kinect titles from 360 to backwards compatible without the work of stripping out the Kinect functionality. They've said this. I also enjoyed the title, and the closest I have now on the Xbox One using Kinect is the Just Dance series.
I've come to love those titles and get a pretty good work out from them as well. At least it's my favorite now that Xbox Fitness is also done. I really liked that zombie fitness workout they had. Was so stupid and fun.

Do you have an xbox one with kinect ?

That's is what is needed for that game

If you have series s or x it won't work

(Unless you are talking about a 360 title then you need xbox 360 with kinect

I haven't seen any plans to make an AC collection. If they ever do that, it will almost certainly done on PC as almost all if not all AC titles have had pc ports. Atleast at first, if they ever do it for Xbox One, it will be after they find a solid method
to make Xbox 360 titles playable on the Xbox One. Still don't expect better graphics on the older titles if they do. They will more than likely be the same exact game, though they may run smoother. It really depends on how microsoft goes with last gen games,
odds are they will be made available on the marketplace slowly over time.

What game is it you are trying to play? Is it a 0g Xbox, Xbox 360, Xbox One or Xbox Series X|S title.
