Global unlock shares from Steam’s own achievement percentages, read on 5 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. . Data by SteamPeaks.com.
Playtime is that of people who reviewed, from the 600 reviews SteamPeaks sampled for Marathon: their total hours when the sample was read, and the hours they had when writing (the refund-window share). Reviewers have usually played more than owners who never wrote a review. Recomputed daily. How this is computed. Data by SteamPeaks.com.
Quieter than 84% of games at month 5.
Monthly averages from the imported archive and SteamPeaks’ own daily rollups after it, Mar 2026 to Aug 2026, each month divided by the launch level (35,040). 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.
