How these estimates are made

Blue Protocol: Star Resonance

Blue Protocol: Star Resonance is estimated to have 2k – 8k players a day. Around 340k – 880k 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.

MU Online

MU Online is estimated to have 62 – 29k players a day. Around 16k – 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.
