How these estimates are made

Project Entropy

Project Entropy is estimated to have 600 – 2k players a day. Around 9k – 24k 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.

Ultima Online

Ultima Online is estimated to have 43 – 20k players a day. Around 18k – 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.
