How these estimates are made

Lost Ark

Lost Ark is estimated to have 18k – 64k players a day. Around 3m – 7m 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.

Thetan Rivals

Thetan Rivals is estimated to have 4 – 2k players a day. Around 2k – 220k 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.
