Holds better than 99% of games at month 71.
Monthly averages from the imported archive and SteamPeaks’ own daily rollups after it, Sep 2020 to Aug 2026, each month divided by the launch level (195). The band is the 25th to 75th percentile of games at each month since launch (13,558 games at launch); the half-life is the first month under half, counting from the month the launch level was set. The projection is the cohort’s band for the next twelve months scaled to this game’s share now: what games usually do next, not a forecast of this game, so it is drawn as a band and labelled an estimate. The axis is cut at 500% of launch; this game reached 3956%. Recomputed weekly, last on 5 Sep 2026. How this is computed. Data by SteamPeaks.com.
