Is there a way to upload your xbox games to xcloud and play them that way instead of having...

Currently no. There's no way to play purchased games through xCloud, so the games would have to be included with xCloud in order to play them through the cloud.

i'd like to, to be honest, but that's the way xcloud wants to work, that you can actually play on your pc and xbox the same games, and you can play them even on your phone

Essentially it's a way for you to play your Xbox through the Cloud so you can use your phone or tablet as a mobile device to play your games.

You can find more information at https://www.xbox.com/xbox-game-streaming/project-xcloud

Well the thing is you still need your xbox for xcloud

As it takes most of the proccessing your phone is only a display in No way would a phone ever have enough power to play games with hdr

Stradia and xcloud relies on cloud proccessing unlike stadia it's not paid service that requires you to buy games stadia requires more bandwidth because you are using google servers for power

Xcloud uses your local xbox and network and live

Xcloud only supports a limited amount of titles and gamepass only

It is upto the publisher to allow it

Should be noted that games take a significant performance hit using xcloud

You can only use gamerpics that are downloaded from the marketplace or taken with the Xbox Live Vision Camera.
