indielist estimates lifetime unit sales for Oxygen Not Included - Spaced Out! at roughly 48,000 to 112,000 copies, with a median around 80,000, derived from its 1,233 Steam reviews using a multi-factor Boxleiter model (version v1.0). That median maps to approximately $595K in net revenue after Steam's 30% cut, regional pricing, and refunds. Unlike black-box trackers, the full calculation is shown on this page: a base review-to-sales multiplier is adjusted for release year, launch price, review sentiment, studio size, and genre, and every adjustment is listed so developers, publishers, and investors can audit exactly how the figure was reached. The range itself reflects genuine uncertainty — review-to-sales ratios vary widely between games — so indielist publishes a low, median, and high band rather than a false-precision single number, and treats free-to-play, heavily discounted, and bundle-distributed titles as having wider error margins still.
