Only 3 reviews so far, so that range swings on one or two people. Read it as a hint, not a measurement.

Copies are estimated from the public review count, adjusted for release year, and cross-checked against SteamSpy's own estimate.

How these numbers were worked out

A hit here: 1,000+ reviews, roughly $150k+ before Steam's cut (a standard indie benchmark).

Copies come from each game's reviews times a sales-per-review rate that falls with release age, from about 31 for the most recent game here to about 43 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
