How these estimates are made
Once Human
Once Human is estimated to have 71k – 250k players a day. Around 2m – 6m accounts have played it in total. The range is anchored on Steam’s official concurrent-player and review counts, then converted to daily actives and accounts — so it covers the Steam player base and will under-count a game played mostly through its own launcher or on console.
Zero King
Zero King is estimated to have 0 – 120 players a day. Around 350 – 41k accounts have played it in total. No Steam data is published for this game, so the range is modelled from the size of its Discord, Reddit, Twitch, YouTube and app-store communities. It is a rough band rather than a measurement.
