Methodology & limitations
Sales estimates use an additive Boxleiter-derived heuristic against public Steam review
counts. They are not authoritative sales data, and the fixed display range
is not a statistically validated confidence interval. Actual results may fall outside it,
especially for deeply discounted or bundle-heavy titles. Algorithm version
v1.0. Read the exact method and validation status.
indielist estimates lifetime unit sales for Halluci-Sabbat of Koishi at roughly 23,000 to 54,000 copies, with a median around 39,000, derived from its 700 Steam reviews using a multi-factor Boxleiter method (version v1.0). That median maps to approximately $176K 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.
