Estimates carry a ±30-50% error range per title. **Measured on 2026-09-17 08:45 UTC.** The whole Steam catalog is re-measured daily; a game that just launched can move a lot between passes. - Steam appid: 5159810 - Developer: Timerlan Galimov - Publisher: Galimov Dynamics - Released: 2026 · Genre: Indie · List price: $18.99 - Deal grade: A (A = dormant with >=$5k/mo opportunity, D = low signal) - Est. net residual revenue: $8.4k to $12.6k per month (mid $10.5k) - Opportunity score: $16.8k/month at x1.60 dormancy multiplier - Est. lifetime owners: 2.6k · Est. lifetime net revenue: $16.8k - Review sentiment: 62% positive across 68 reviews (66 from Steam purchases) - Review velocity: 66.0 reviews/month (6-month average) ## Why it's flagged - No developer announcement on record, ever - Last build shipped 0 months ago ## Where a gross dollar goes (monthly, at current velocity) | Stage | USD/month | |---|---| | Gross storefront sales | $19.1k | | After VAT / sales tax (-13% blended) | $16.6k | | After refunds (-9.5% median) | $15.0k | | Net to developer (after Steam 30%) | $10.5k | ## Estimated acquisition range $252.0k to $504.0k (2-4x the trailing net annuity of $126.0k/year). Same error range applies. ## Markets by review language - german: 2% - english: 52% - russian: 42% - spanish: 2% (game NOT localized in this language) - brazilian: 3% (game NOT localized in this language) ## 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.
