Review count and SteamSpy's owner range disagree, so the band is widened to cover both rather than picking a favourite. Multiplied by $14.14, the average price these copies actually sold for — weighted from the price history rather than taken from the $14.99 launch price. That is 6% below list price on average. Before Steam's cut, VAT and refunds. How these numbers are calculated.
