Review count and SteamSpy's owner range agree well enough to narrow the estimate down to this band. Multiplied by $15.21, the average price these copies actually sold for — weighted from the price history rather than taken from the $17.99 launch price. That is 15% below list price on average. Before Steam's cut, VAT and refunds. How these numbers are calculated.

History
3 data points since Aug 3, 2026. Gaps mean nothing changed — the value carries forward.
The blurred area is the rest of the history. 53 further data points reach back to Feb 14, 2025 — 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: $14.39 on Feb 14, 2025.
