How these estimates are made
Diablo IV
Diablo IV is estimated to have 36k – 130k players a day. Around 1m – 3m 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.
Project Cataclysm
Project Cataclysm is estimated to have 9 – 4k players a day. Around 5k – 480k 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.
