Concurrent players on Steam, one reading a day at about 15:00 UTC since Aug 13, 2026. Before then readings were taken at different times of day, spanning 21 hours, and Steam concurrency runs about 1.8x higher at its daily high than at its low — so some of the movement across that stretch is the clock, not the game.
