@TPG Although there are similarities, there are also important differences. Both host the computing power, and off-set the display through a high-speed connection. However, Stadia provides access to the games on their own store, while Shadow provides a remote Windows 10 computer (on which you can install all the application stores such as Steam, Origin, Uplay etc.) as well as applications that are not necessarily games but require computing power, such as Photoshop, 3DS max etc.
