Global unlock shares from Steam’s own achievement percentages, read on 12 Sep 2026, ordered most common first. The finish rules (beat the game, completed the story, final boss, credits, epilogue and their variants) matched no name or description, so the funnel has no finish step rather than a guessed one. Shares are of players who have the game on their account, as Steam counts them. How this is computed. Data by SteamPeaks.com.
Holds better than 63% of idler games at month 6.
Monthly averages from the imported archive and SteamPeaks’ own daily rollups after it, Feb 2026 to Aug 2026, each month divided by the launch level (213). The band is the 25th to 75th percentile of idler games at each month since launch (46 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 idler games usually do next, not a forecast of this game, so it is drawn as a band and labelled an estimate.
