Global unlock shares from Steam’s own achievement percentages, read on 7 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. How this is computed. Data by SteamPeaks.com.

Streamer Effect

Do streams move Terraforming Mars?

Every game How this is computedNot sampled

Terraforming Mars is not in the Twitch ring: viewers are sampled every 10 minutes for the hundred most played games and every watched game (364 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.

Best Time to Play

When Terraforming Mars is busiest

How this is computedHourly sample 41 minutes ago

Needs four weeks of hourly samples, 2 on file (70 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.

Monthly averages from the imported archive and SteamPeaks’ own daily rollups after it, Oct 2018 to Aug 2026, each month divided by the launch level (303). The band is the 25th to 75th percentile of strategy games at each month since launch (22 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.
