Just a thought in my opinion Stadia should offer games playable from Googles Play Store.
Not sure about you but I would enjoy playing Mobile games through the Stadia and the amazing Controller it has!
Cause who in the right mind would want to play in a wee rectangle on ur tv screen
Optimized for full screen just like the Stadia.
I think your missing the point here.
But that would be up to the game developers and if they went through that hassle it probs works on android tv so what's the point
