For sure I definitely see that, but I think Stadia solves a different problem. If you are already heavily invested in something like Steam and have the hardware, Stadia doesn't really solve your problem. If you don't have the hardware, maybe the computer you can afford is a $200 netbook, or you can't travel with your gaming PC, but can pay the monthly fee and occasionally the cost of a game, then Stadia could solve the problem, barring a good enough internet connection. Which when I tried it was my case. I didn't have a gaming PC, I just bought an M1 Macbook Air, so didn't really wanna dish out more money for hardware, Stadia could have allowed me to game on my M1, but once again, bad internet connection. How I play locally and have games on Steam since my job provided me with a home gaming PC and they don't care what I do with it so long as I can work from home with it (no company spyware).

But yea, if you have the hardware already, the value add wasn't really there. But for the broke college student, or broke adult who can't justify dropping hundreds/thousands today but can eat a few bucks a month. Or someone who travels often for personal or work, then the value add is there.
