my reasoning is that if they would not have added unofficial controller support for stadia, all people playing on stadia would have been forced to play on pc with MK.... So yes, I prefer a buggy partially working thing instead of it being omitted because not 100% finished...
Thanks for your swift response.
I will have to learn to make my peace with how things are on Stadia currently, but given that at the very top of this page it says, "Early Access Available Now" for Steam, Stadia, and Gog.com, in my opinion selling the game implies that support for all platforms would be equal. But that is just me!
