Review count and SteamSpy's owner range agree well enough to narrow the estimate down to this band. Multiplied by $0.93, the average price these copies actually sold for — weighted from the price history rather than taken from the $0.99 launch price. That is 6% below list price on average. Before Steam's cut, VAT and refunds. How these numbers are calculated.

History
2 data points since Aug 5, 2026. Gaps mean nothing changed — the value carries forward.
The blurred area is the rest of the history. 145 further data points reach back to Feb 1, 2019 — 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: $0.49 on Jun 26, 2019.
