Holds better than 83% of games with no tags on file at month 166.
Monthly averages from the imported archive and SteamPeaks’ own daily rollups after it, Aug 2012 to Jun 2026, each month divided by the launch level (18). The band is the 25th to 75th percentile of games with no tags on file at each month since launch (10,467 games at launch); the half-life is the first month under half, counting from the month the launch level was set. No projection: the cohort has no curve twelve months beyond this game’s age. Recomputed weekly, last on 5 Sep 2026. How this is computed. Data by SteamPeaks.com.
