# Dungeons And Cat > ResidualPlay case file: an overlooked Steam game still earning residual revenue. Estimates carry a ±30-50% error range per title. **Measured on 2026-08-29 20:57 UTC.** The whole Steam catalog is re-measured daily; a game that just launched can move a lot between passes. - Steam appid: 1526540 - Developer: CatBellUnion - Publisher: Mango Party - Released: 2026 · Genre: Action · List price: $9.99 - Deal grade: C (A = dormant with >=$5k/mo opportunity, D = low signal) - Est. net residual revenue: $3.6k to $5.4k per month (mid $4.5k) - Opportunity score: $4.5k/month at x1.00 dormancy multiplier - Est. lifetime owners: 2.2k · Est. lifetime net revenue: $7.5k - Review sentiment: 93% positive across 60 reviews (56 from Steam purchases) - Review velocity: 54.1 reviews/month (6-month average) ## Why it's flagged - Developer active, last post 0 months ago - Studio active elsewhere (5 titles tracked), so this one may welcome a partner - Last build shipped 0 months ago ## Where a gross dollar goes (monthly, at current velocity) | Stage | USD/month | |---|---| | Gross storefront sales | $8.2k | | After VAT / sales tax (-13% blended) | $7.2k | | After refunds (-9.5% median) | $6.5k | | Net to developer (after Steam 30%) | $4.5k | ## Markets by review language - japanese: 3% - schinese: 56% - brazilian: 3% (game NOT localized in this language) - english: 23% - koreana: 15% (game NOT localized in this language) Localization gap: 18% of measured reviews are written in languages the game does not support (top: koreana). 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.
