Also, considering adapting a game for Stadia takes non-negligible amount of time: 1. Before they released Stadia, they could only work with a small handful of developers without too much getting leaked. 2. Now that it's public, it takes time for all the devs to port their games. They did announce that there will be 120+ games in 2020, which matches up with my point above. Most of those probably only started porting mid 2019. Furthermore, if compared to consoles, and not decades of PC history, Stadia does have a reasonable number of games at "launch", though not enough exclusives.
