How these estimates are made

MU Online

MU Online is estimated to have 72 – 33k players a day. Around 17k – 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.

Sea of Thieves

Sea of Thieves is estimated to have 22k – 79k players a day. Around 4m – 11m 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.
