How these estimates are made

Aliens Online

Not enough data collected to estimate this game yet.

Once Human

Once Human is estimated to have 54k – 190k 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.
