How these estimates are made

Atlas Reactor

We estimate that about 430 people play Atlas Reactor on a typical day (most likely between 99 and 1,300), based on data from Nov 13, 2026. Around 190,000 accounts (between 140,000 and 240,000) have played it at some point. Atlas Reactor is on Steam, but Steam covers only part of its players, so the estimate also draws on the size of its Discord, Reddit, Twitch, YouTube and app-store communities. Confidence: low — a community-size model, not a measurement.

Wurm Unlimited

We estimate that about 500 people play Wurm Unlimited on a typical day (most likely between 360 and 690), based on data from Nov 13, 2026. Around 77,000 accounts (between 60,000 and 99,000) have played it at some point. It is anchored on Steam’s official concurrent-player count, converted to daily players, so players on other launchers or consoles may not be fully counted. Confidence: medium — Steam covers part of the player base, or several community signals agree.
