How these estimates are made

Blue Protocol: Star Resonance

Blue Protocol: Star Resonance is estimated to have 2k – 7k 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.

Rusty Hearts

Rusty Hearts is estimated to have 2 – 750 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.
