Hours, Honestly

How long people play Book of Demons

Every game How this is computedNot computed yet

Sample too small: no sampled review with a playtime on file, 30 needed before the figures are written. The reviews poller samples each game’s reviews in turn; the funnel job reads them daily.

Finish funnel · achievements by global unlock share

No funnel yet

Book of Demons lists 202 achievements, but their global unlock shares have not been read yet; the achievements poller reaches every game with achievements in turn, and the funnel job orders them the next day.

Best Time to Play

When Book of Demons is busiest

How this is computedHourly sample 14 Sep 2026, 13:00 UTC

Needs four weeks of hourly samples, 3 on file (192 hourly rows since 6 Sep 2026, 07:00 UTC). The weekly activity job writes the profile once 4 distinct weeks fall inside its 8-week window; the fourth week of samples begins on 21 Sep 2026, so the heatmap can appear with the job’s first run after that.

Streamer Effect

Do streams move Book of Demons?

Every game How this is computedNot sampled

Book of Demons is not in the Twitch ring: viewers are sampled every 10 minutes for the hundred most played games and every watched game (371 games since 3 Sep 2026), so there is no viewer series to set against its players yet. Watching the game adds it to the ring.

Lifespan

How games like Book of Demons hold their players

Every game How this is computedCurves computed 12 Sep 2026, 15:26 UTC

Book of Demons’s monthly averages begin in Apr 2016, more than two months after its 13 Dec 2018 release, so its series is not a launch curve and the job leaves it off rather than measure from the wrong start. The cohort’s own curve is shown.

Share of the launch level by month since launch · games · 21,874 games at launch

Middle half of gamesMedian gamesHalf of launch

The band is the 25th to 75th percentile share of the launch level among games at each month since launch, with their median as the line; a game joins a curve after 6 months of averages. Recomputed weekly, last on 12 Sep 2026. How this is computed. Data by SteamPeaks.com.
