Stadia!

Good Morning. Stadia seems to be bullshit compared to xcloud. Better wait for xcloud.

Stadia +
The Basic version is free
The Pro version (10 Dollar/month) adds games to your library every month

Stadia -
The Basic Version does not add games to your library every month and you have to pay for any new game
No one knows what type of games will be added every month

Xcloud +
If you own a Access-pass (3 Dollar/month) you get access to more than 200 Games in the library
If you own a access-pass you can start playing right away, with the xcloud servers. No extra fees

xcloud -
No basic (Free) versions available
