I don't think Google is going to want to talk about how many Stadia accounts there are publicly until it becomes a MUCH more sizable number than whatever it is right now.
Mhhh I can't imagine that for the total playerbase, but it would be nice to see the actual players online at the moment. Because of privacy of course not their usernames, but e.g.
What are Stadians playing?
This might be an indicator for people to join or purchase games that are popular regarding your idea of a growing playerbase. I could imagine something like that coming or at least to see where your friends are online in which games, that would be helpful as well, no? ![]()
