That said, I haven't played any multiplayer FPS games. The multiplayer games I did play seemed totally fine, though "seems totally fine" is obviously a subjective observation.
The biggest gripe I had was that you couldn't use your Steam library or bring your own games in any way. The fact that they're refunding purchases is kind of amazing. Knowing Google, I assumed that when Stadia shut down, that'd be it, and I was ok with that.
For comparison, I also subscribed to GeForce Now. Technologically, it’s basically… remote desktop to Steam? From a dedicated client application. Everything felt hacked-together. Sometimes the language was wrong, sometimes the resolution. Almost every time I had to re-login to Steam. Performance was so-so, sometimes with ridiculous lag and video encoding errors. Oh yeah and waiting times, lol.
I have not tried the Xbox cloud gaming thingy yet, I imagine it could be more like Stadia.
I think Google made a good choice with customized game versions for Stadia. Not using Windows then was good, too. The custom hardware? Probably not so much. Either way, the customized game versions were also what killed Stadia. Establishing a new platform and getting software on it is very hard.
Stadio was awesome. It also never had a chance.
For the casual gamer, cloud gaming is perfect - no large downloads, play from your TV or your PC or your iPad/phone when you have 30 minutes free and don't want to buy/build/maintain a PC or Console.
That said, I haven't played in around a year. The games catalog was too limited and they never got any of the AAA games (Call of Duty, EA games etc)
They released the LG app for Stadia less than a year ago, and so having it on my TV with no additional equipment was a god-send. I could play Jackbox when friends either in my living room, or with my remote team at work. I still had the Chromecast, so then I could spin up any game from basically any room in my house and I just needed the controller.
I mean, this is what everyone claimed was going to happen from the beginning... I'm just bummed because I quite enjoyed the ride.
Currently I use xcloud, its "acceptable" with certain games that don't require low latencies but its picture quality in particular is ass in comparison to Stadia. RIP.
