Holds better than 57% of games with no tags on file at month 9.
Monthly averages from the imported archive and SteamPeaks’ own daily rollups after it, Nov 2025 to Aug 2026, each month divided by the launch level (12). 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. The projection is the cohort’s band for the next twelve months scaled to this game’s share now: what games with no tags on file usually do next, not a forecast of this game, so it is drawn as a band and labelled an estimate.
