Review count and SteamSpy's owner range disagree, so the band is widened to cover both rather than picking a favourite. Multiplied by $13.85, the average price these copies actually sold for — weighted from the price history rather than taken from the $14.99 launch price. That is 8% below list price on average. Before Steam's cut, VAT and refunds. How these numbers are calculated.

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. 222 further data points reach back to Dec 1, 2016 — 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.

Lowest recorded price: $5.99 on May 2, 2022.
