McOsu lists no achievements on its store page, so there is no unlock share to order and no funnel to draw.

Best Time to Play

When McOsu is busiest

How this is computedHourly sample 53 minutes ago

Needs four weeks of hourly samples, 2 on file (57 hourly rows since 5 Sep 2026, 08:00 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.

Every game How this is computedNot sampled

McOsu is not in the Twitch ring: viewers are sampled every 10 minutes for the hundred most played games and every watched game (351 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.

Monthly averages from the imported archive and SteamPeaks’ own daily rollups after it, Mar 2017 to Aug 2026, each month divided by the launch level (49). 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.
