Can you compare daily active users to peak simultaneous users? Seems like apples to oranges. 150 million DAU could easily be the same as 45 million peak online.

Also how believable are both Steam and Roblox's numbers with regard to bot accounts? I have no idea about this, I'm biased towards Steam but based on the HN comments every time Roblox comes up I get the vibes that they are a comparatively less ethical company that might be willing to push the boundaries of ignoring bots for the sake of better metrics to impress investors. Also this isn't data at all but the steam games I play wouldn't benefit from bots, but I could see players of some of the silly little games my kids play in Roblox benefit from having some bot accounts to help you.
