Global unlock shares from Steam’s own achievement percentages, read on 10 Nov 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.
Playtime is that of people who reviewed, from the 200 reviews SteamPeaks sampled for Cepheus Protocol: 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.
Holds better than 98% of sandbox games at month 77.
Monthly averages from the imported archive and SteamPeaks’ own daily rollups after it, May 2020 to Oct 2026, each month divided by the launch level (14). The band is the 25th to 75th percentile of sandbox games at each month since launch (48 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. The axis is cut at 500% of launch; this game reached 866%. Recomputed weekly, last on 7 Nov 2026. How this is computed.
