Sort of an extension of this: does Google Stadia availability imply an official build for linux? Are they under some kind of exclusivity agreement with regards to a linux version?
Just Dance 2020/2021 is a good example of this: the PC version was discontinued in 2017, but 2020 and 2021 were also released on Stadia -- without an accompanying PC build.
It is about the only linux release I've never managed tu run.
There's always someone really, incredibly angry on the Internet.
