Estimates carry a ±30-50% error range per title. **Measured on 2026-08-30 05:37 UTC.** The whole Steam catalog is re-measured daily; a game that just launched can move a lot between passes. - Steam appid: 4932620 - Developer: Ashforge Games - Released: 2026 · Genre: Adventure · List price: $4.99 - Deal grade: C (A = dormant with >=$5k/mo opportunity, D = low signal) - Est. net residual revenue: $1.0k to $1.6k per month (mid $1.3k) - Opportunity score: $1.3k/month at x1.00 dormancy multiplier - Est. lifetime owners: 1.7k · Est. lifetime net revenue: $2.8k - Review sentiment: 68% positive across 57 reviews (42 from Steam purchases) - Review velocity: 30.9 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 3 language(s) ## Where a gross dollar goes (monthly, at current velocity) | Stage | USD/month | |---|---| | Gross storefront sales | $2.3k | | After VAT / sales tax (-13% blended) | $2.0k | | After refunds (-9.5% median) | $1.8k | | Net to developer (after Steam 30%) | $1.3k | ## Markets by review language - english: 8% - koreana: 3% (game NOT localized in this language) - schinese: 89% ## 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.
