These estimates use the Boxleiter method, a widely-used industry approach that estimates game sales from the number of Steam reviews.

Factors that affect accuracy:

• Review-to-purchase ratio varies by genre
• Discount history - games with frequent deep sales may have higher ratios
• Regional pricing - different prices in different markets are not captured
• Refunds - Steam's return policy means some counted sales were refunded
• Bundled sales - keys sold through third-party bundles may not generate reviews

We provide a confidence range ($9,089,864 to $27,269,592) to reflect this uncertainty. For the best estimate we combine the Boxleiter range with a calibrated midpoint (x29) and a calibrated ASP of $40.
