Review count and SteamSpy's owner range agree well enough to narrow the estimate down to this band. Multiplied by the $9.99 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
5 data points since Aug 4, 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.
Lowest recorded price: $9.99 on Sep 25, 2026. That is the current price.
