No, I'm Not a Human has already hit a peak of over 124,000 viewers watching it at once on Twitch. So far, the game's reception on Steam has been more muted, with a current peak of 8,248 players. But this is a single-player game rather than a multiplayer title, which may be why it hasn't done as well on Steam yet.
However, it's important to note that neither of those metrics gives as complete a picture as some Internet discussions suggest they do; Civilization VII launched on other platforms and game stores like the PlayStation 5, Xbox, Nintendo Switch, and Epic Game Store, and those wouldn't be captured in Steam numbers-even though it intuitively seems likely that Steam would account for the significant majority of players for this particular franchise. Twitch viewership is also not necessarily representative of sales or the number of players.
