Please correct me if I am wrong. Don't I need to still buy a Stadia controller to play these games, even if they are otherwise free?
Anyway, they look like decent enough games. The Pac Man one looks the best to me and the other 2 games look like they are worth a try. However, I can't say that any of these games has me super excited. For me the issue with Stadia, and streaming services in general, is that my wallet is not the limiting factor to playing games. For me, it is time. I already have more than enough games to play, but I don't have time to play them all. While I like cheaper gaming, that is not my first goal. My first goal is to find the games that I will enjoy the most and then play them. Stadia doesn't have anything that would compete with Breath of the Wild, which is the game that I like most from the current systems.
