There are a lot, a lot of reason why I don’t believe Stadia or services like it are some inevitable future… mods is one of them. Private servers is another. And that’s assuming the tech can actually be on par with everything else which appears not to be the case. But hey I’ve been watching guys in the industry as well as enjoying the industry convince themselves that everyone wants the SAMETHING followed by them scratching their head when that’s not actually true.
I am sure there is a market for this, but there is nothing with this Google experiment that has said it’s even close to some universal want.
