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 SULFUR at roughly 349,000 to 815,000 copies, with a median around 582,000, derived from its 8,960 Steam reviews using a multi-factor Boxleiter method (version v1.0). That median maps to approximately $8.3M 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.

Ecosystem
indielist positions SULFUR within the Action segment so players can surface comparable titles by shared tags and genre rather than by storefront promotion. On the developer side, Perfect Random's other releases and Perfect Random's wider catalog are one click away, letting developers benchmark where SULFUR sits among a studio's body of work and how its publisher's portfolio performs. Because indielist maps studios, publishers, games, and funding into one connected graph, the same SULFUR page serves three audiences at once: players hunting their next Action game, developers studying how comparable projects were positioned and what they sold, and investors tracing which teams and labels are active in the space. A machine-readable markdown mirror of this page is published at the same path with a .md suffix for AI assistants, and its review, price, and sales-estimate figures are refreshed on a schedule rather than frozen at launch.
