Playtime is that of people who reviewed, from the 600 reviews SteamPeaks sampled for Halo: The Master Chief Collection: 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.
Viewers are Twitch’s counts for the game’s category, sampled by SteamPeaks every 10 minutes; players are SteamPeaks’ own counts, averaged onto the same bins. The correlation is the strongest over lags from six hours before to six hours after; a lift compares the six hours after a spike with the same six hours a week earlier and is an estimate, shown beside its baseline. Correlation is not causation: the figures say how closely the two series move together, not that one caused the other. Verdict from the daily job, run 10 Sep 2026, 15:28 UTC, over 1 day of both series. How this is computed. Data by SteamPeaks.com.
Viewer counts from Twitch.
Global unlock shares from Steam’s own achievement percentages, read on 10 Sep 2026, ordered most common first. The finish step is the lowest-share achievement whose name or description matched the finish rules (name-or-description matches the finish rules). 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 79% of games at month 80.
Monthly averages from the imported archive and SteamPeaks’ own daily rollups after it, Dec 2019 to Aug 2026, each month divided by the launch level (24,749). 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. No projection: the cohort has no curve twelve months beyond this game’s age. Recomputed weekly, last on 5 Sep 2026. How this is computed. Data by SteamPeaks.com.
