Review count and SteamSpy's owner range agree well enough to narrow the estimate down to this band. Multiplied by the $39.99 launch price — there is not enough price history for this game to weight the copies by what they actually sold for. Before Steam's cut, VAT and refunds. How these numbers are calculated.

History
8 data points since Jul 27, 2026. Gaps mean nothing changed — the value carries forward.
The revenue curve is an estimate, not a measurement. It is the only calculated series here: each interval takes the review growth of that period, multiplies it by the sales-per-review factor and by the price actually charged at the time, and adds the result to the running total. That is why it climbs more slowly through discount periods than the review curve next to it. The last point is the same figure quoted above — gross, before Steam's cut, VAT and refunds. How these numbers are calculated.
The blurred area is the rest of the history. 67 further data points reach back to Feb 22, 2024 — your plan shows the last 90 days of it. How far each series in particular reaches is written on its own chart; not every one of them goes back that far. The shape in the blurred area is decoration, not data: the figures are not in this page at all. Plus unlocks the complete series.
The dashed line marks Jul 28, 2026, when steamlense started measuring. Everything to its left was backfilled from public sources — monthly review counts from Steam, price changes from IsThereAnyDeal, monthly player averages from SteamCharts. Those are monthly figures, so the curve is coarser there — one point a month instead of one a day.
Lowest recorded price: $14.79 on Jun 25, 2026.
