I think they gave up on it before ever really giving it a chance to be honest, easy to say in hindsight but they should’ve not announced anything before they had some big AAA games from their few Google Game Studios (all closed now) to launch with.
I was a day 1 adopter but never really used it all that much beyond the first 2-3 months to be honest, most of the stuff on there was ports of PS4/XB1 games I’d already played, the one exclusive I did play and finish was Gylt, which I really enjoyed as a more cartoony Silent Hill almost. But it was a smaller title and not a flagship release the service needed.
Overall, it needed some proper commitment and money spent on it in terms of investment in studios, buying some timed exclusives and patience from Google and they never wanted to give it any of that.
From my experience of the service, it was excellent and I never had any issues from latency or all that jazz, everything ran superbly and looked as good if not a little better than the last gen systems at the time.
But yeah, an unmitigated disaster that was doomed to fail from the beginning thanks to Google not wanting to dive into its funds as much as it should’ve done and the world just not really wanting or being ready for a streaming service.
I sold all my stuff for it aside from the controller back in 2020 and have never really thought about it since.
