Stadia's shutdown reallly pissed me off. The problem it had was the monitisation, not the actual thing it did. Stadia worked in places with crappy wifi, like the 2.4ghz only I had at my Mam's house, when GeForce Now, XBox Cloud and Amazon's Luna, all shit the bed. Really well optimised, it also worked at higher quality than everything else when you actually had a good connection.
If they'd actually built out the infrastructure properly, had all the features, like being able to play a game via youtube after watching a video on it, and the quasi split screen thing, it would've done a lot better. It also needed a bit of time, which Google seems hesitant to actually give any of it's projects.
I played it. I know how cool jetpack kneepads are!
