Q: What is the Boxleiter Method?
The Boxleiter Method estimates the number of Steam game units sold by using the number of public Steam Reviews. It assumes that for each Steam Review, there will be between 20 and 60 sales. This number – called the NB number – is an assumption based on data from surveyed Steam developers and publishers. It changes genre-to-genre and year-to-year as different player-personas leave reviews more-or-less often on the games they like. For simplicity, however, the overall average is used to smooth out outliers.
