> I really don't remember a plethora, rather some games
Ubisoft's whole catalogue going all the way back to Black Flag, RDR2, EA's latest titles (FIFA, Star Wars), Cyberpunk, and tons of indie games (I had Premium, every month I got ~2 new indie games; by the end I had something like 50+ games).
Go search for last edition of Stadia developer conference, where something like Proton for Stadia was announced, alongside the acknowledgement it wasn't working as expected.
