# RIG Riot > ResidualPlay case file: an overlooked Steam game still earning residual revenue. Estimates carry a ±30-50% error range per title. **Measured on 2026-09-15 08:10 UTC.** The whole Steam catalog is re-measured daily; a game that just launched can move a lot between passes. - Steam appid: 3180340 - Developer: Sage Boatman - Released: 2026 · Genre: Action · List price: $19.99 - Deal grade: A (A = dormant with >=$5k/mo opportunity, D = low signal) - Est. net residual revenue: $12.3k to $18.5k per month (mid $15.4k) - Opportunity score: $20.1k/month at x1.30 dormancy multiplier - Est. lifetime owners: 3.8k · Est. lifetime net revenue: $25.2k - Review sentiment: 93% positive across 96 reviews (94 from Steam purchases) - Review velocity: 92.0 reviews/month (6-month average) ## Why it's flagged - Developer active, last post 0 months ago - Last build shipped 0 months ago - Store page localized in only 1 language(s) ## Where a gross dollar goes (monthly, at current velocity) | Stage | USD/month | |---|---| | Gross storefront sales | $28.0k | | After VAT / sales tax (-13% blended) | $24.3k | | After refunds (-9.5% median) | $22.0k | | Net to developer (after Steam 30%) | $15.4k | ## Estimated acquisition range $369.6k to $739.2k (2-4x the trailing net annuity of $184.8k/year). Same error range applies. ## Markets by review language - japanese: 2% (game NOT localized in this language) - brazilian: 1% (game NOT localized in this language) - german: 1% (game NOT localized in this language) - english: 92% (game NOT localized in this language) - russian: 1% (game NOT localized in this language) - spanish: 2% (game NOT localized in this language) Localization gap: 100% of measured reviews are written in languages the game does not support (top: english). Localizing is likely immediate market expansion. ## Methodology Units are estimated from Steam-purchase reviews times a release-cohort multiplier, 40-75x by year. Cohorts from 2020 on are calibrated against 182 sales milestones announced by developers; older ones follow the published Boxleiter tables. Revenue uses an effective price (lifetime discounts and regional pricing) and nets out VAT (~13%), refunds (~9.5%) and Steam's 30% cut: roughly 55% of gross reaches the developer.
