# Touhou Desktop Pet > ResidualPlay case file: an overlooked Steam game still earning residual revenue. Estimates carry a ±30-50% error range per title. **Measured on 2026-08-30 08:00 UTC.** The whole Steam catalog is re-measured daily; a game that just launched can move a lot between passes. - Steam appid: 4653120 - Developer: TouhouFans - Released: 2026 · Genre: Casual · List price: $0.99 - Deal grade: D (A = dormant with >=$5k/mo opportunity, D = low signal) - Est. net residual revenue: $234 to $351 per month (mid $292) - Opportunity score: $292/month at x1.00 dormancy multiplier - Est. lifetime owners: 1.5k · Est. lifetime net revenue: $505 - Review sentiment: 100% positive across 41 reviews (38 from Steam purchases) - Review velocity: 35.2 reviews/month (6-month average) ## Why it's flagged - Developer active, last post 0 months ago - Last build shipped 0 months ago - Last discounted 0 months ago, 1 sales in the last 12 months ## Where a gross dollar goes (monthly, at current velocity) | Stage | USD/month | |---|---| | Gross storefront sales | $530 | | After VAT / sales tax (-13% blended) | $461 | | After refunds (-9.5% median) | $417 | | Net to developer (after Steam 30%) | $292 | ## 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.
