Yeah, if it was truly a cheap port that was just putting the game on another store and plugging in some API calls, devs would have flocked to it. But it involved a pretty involved linux ports instead. Apparently Red Dead Redemption 2 cost tens of millions to get working on Stadia.

sucks to hear as someone who wants linux gaming to get more prominance, but I guess for now the current direction is to WINE it out.
