I discovered cloud gaming through Stadia but I now direct all of my attention towards GFN and, for the lack of availability of Shadow and equivalent, to G4dn instances on AWS with Parsec.

It's definitely great to be able to get games on sale on various platforms and then rent hardware to play it on my laptop. Even with pretty heavy costs on AWS I'm still very satisfied (spot instances + one ebs-backed snapshot for the AMI + bandwidth out costs = about 1 CAD/hr played with about $10 of fixed costs). Even if I played a hundred hours per month on AWS, it would barely reach the cost of a basic desktop by the end of a year, let alone anything that has RTX cards. And I'd have to do it all over again soon as specs requirements increase.

I appreciate the ease of use of Stadia but I definitely hope that in this fight it's the generic cloud-computing crowd that wins.

I've said it before and I'll say it again: I'd recommend GFN to literally everyone I know if they stopped limiting what games I can play on it. It's really very nice for what it actually works for.
