# Parry Survivor > 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 13:01 UTC.** The whole Steam catalog is re-measured daily; a game that just launched can move a lot between passes. - Steam appid: 4540130 - Developer: Seal - Released: 2026 · Genre: Action · List price: $7.99 - Deal grade: A (A = dormant with >=$5k/mo opportunity, D = low signal) - Est. net residual revenue: $1.9k to $2.9k per month (mid $2.4k) - Opportunity score: $5.1k/month at x2.10 dormancy multiplier - Est. lifetime owners: 1.4k · Est. lifetime net revenue: $3.9k - Review sentiment: 100% positive across 36 reviews (36 from Steam purchases) - Review velocity: 36.0 reviews/month (6-month average) ## Why it's flagged - No developer announcement on record, ever - Studio active elsewhere (2 titles tracked), so this one may welcome a partner - Last build shipped 0 months ago - No Steam discount in 4.0 years (deepest tracked: -0%) ## Where a gross dollar goes (monthly, at current velocity) | Stage | USD/month | |---|---| | Gross storefront sales | $4.4k | | After VAT / sales tax (-13% blended) | $3.8k | | After refunds (-9.5% median) | $3.4k | | Net to developer (after Steam 30%) | $2.4k | ## Estimated acquisition range $57.8k to $115.7k (2-4x the trailing net annuity of $28.9k/year). Same error range applies. ## Markets by review language - schinese: 100% ## 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.
