Review count and SteamSpy's owner range agree well enough to narrow the estimate down to this band. Multiplied by $4.99, the average price these copies actually sold for — weighted from the price history rather than taken from the $4.99 launch price. Before Steam's cut, VAT and refunds. How these numbers are calculated.
