Methodology & limitations
Sales estimates use a multi-factor Boxleiter method against public Steam review counts.
They are not authoritative sales data. Actual sales can deviate by
±50% in either direction. Free-to-play games, deeply discounted titles, and games
with heavy bundle distribution have larger error margins. Algorithm version
v1.0.
indielist estimates lifetime unit sales for ONE PIECE: PIRATE WARRIORS 4 at roughly 973,000 to 2.3 million copies, with a median around 1.6 million, derived from its 21,631 Steam reviews using a multi-factor Boxleiter method (version v1.0). That median maps to approximately $37.1M 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.
