The other thing is - they must, must be playing the multi-year long game here. Infrastructure around the world just isn't ready for game streaming.
Having said that, from what I hear GeForce Now is giving people a FAR better experience than Stadia.
Now that I think about it, why did they even rush Stadia out? I never got the impression anyone was dying to get their hands on it. They could have given it another year of polish at least and nobody would have complained, surely?
I'd love to hear Google's internal rationale for why they thought this pricing model was a good idea.
