How these estimates are made

Aion

Aion is estimated to have 79 – 37k players a day. Around 24k – 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.

Phantasy Star Online 2

Phantasy Star Online 2 is estimated to have 3k – 9k players a day. Around 430k – 1m 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.
