Steam doesn't publish sales. These estimates multiply the number of reviews by a factor that depends on the release year (the Boxleiter method). Net revenue is what's left of list price × sales after refunds, regional pricing, discounts, sales tax and Steam's 30% cut, before any publisher's share. Treat them as a ballpark for comparing games, not as reported figures.
