Review count and SteamSpy's owner range agree well enough to narrow the estimate down to this band. Multiplied by $22.19, the average price these copies actually sold for — weighted from the price history rather than taken from the $24.99 launch price. That is 11% below list price on average. Before Steam's cut, VAT and refunds. How these numbers are calculated.
