# Fireboy & Watergirl 1: The Forest Temple > ResidualPlay case file: an overlooked Steam game still earning residual revenue. Estimates carry a ±30-50% error range per title. **Measured on 2026-09-01 20:13 UTC.** The whole Steam catalog is re-measured daily; a game that just launched can move a lot between passes. - Steam appid: 5084260 - Developer: Oslo Albet - Released: 2026 · Genre: Action · List price: $0.99 - Deal grade: B (A = dormant with >=$5k/mo opportunity, D = low signal) - Est. net residual revenue: $266 to $400 per month (mid $333) - Opportunity score: $533/month at x1.60 dormancy multiplier - Est. lifetime owners: 1.7k · Est. lifetime net revenue: $571 - Review sentiment: 91% positive across 45 reviews (43 from Steam purchases) - Review velocity: 40.1 reviews/month (6-month average) ## Why it's flagged - No developer announcement on record, ever - Studio active elsewhere (4 titles tracked), so this one may welcome a partner - Last build shipped 1 months ago ## Where a gross dollar goes (monthly, at current velocity) | Stage | USD/month | |---|---| | Gross storefront sales | $605 | | After VAT / sales tax (-13% blended) | $526 | | After refunds (-9.5% median) | $476 | | Net to developer (after Steam 30%) | $333 | ## Estimated acquisition range $8.0k to $16.0k (2-4x the trailing net annuity of $4.0k/year). Same error range applies. ## Markets by review language - english: 19% - koreana: 7% (game NOT localized in this language) - russian: 36% - spanish: 7% - schinese: 29% (game NOT localized in this language) - brazilian: 2% (game NOT localized in this language) Localization gap: 38% of measured reviews are written in languages the game does not support (top: schinese). 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.
