When people play
Average concurrent players by day and hour over the last 15 days, shown in .
Daily activity peaks around 20:00 — a pattern consistent with a player base concentrated in Europe, the Middle East & Africa, with a second wave suggesting a sizable audience in East & Southeast Asia. Steam publishes no per-country player data, so this is inferred from play times.
