How these estimates are made

Once Human

Once Human is estimated to have 66k – 230k 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.

Phantasy Star Online

Phantasy Star Online is estimated to have 23 – 11k players a day. Around 15k – 2m 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.
