I gave Stadia a try a while back.

It worked really well, but I was instantly disappointed by the game selection. When you advertise being able to play the latest, coolest games to me, I expect there to be a selection of the coolest, latest, games. I was really thinking I'd be able to play the latest, Doom incarnation and such. If I recall correctly, Doom was there but at a separate additional cost that made it very unattractive to me.

I think I did the free trial plus one addition month of paid before I gave up on it.
