Review count and SteamSpy's owner range agree well enough to narrow the estimate down to this band. Multiplied by the $5.99 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
2 data points since Oct 4, 2026. Gaps mean nothing changed — the value carries forward.
The blurred area is the rest of the history. 1 further data points reach back to Aug 5, 2026 — 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: $5.09 on Oct 4, 2026. That is the current price.
