# Train Sim World® 7 > ResidualPlay case file: an overlooked Steam game still earning residual revenue. Estimates carry a ±30-50% error range per title. **Measured on 2026-09-11 15:33 UTC.** The whole Steam catalog is re-measured daily; a game that just launched can move a lot between passes. - Steam appid: 4678800 - Developer: Dovetail Games - Publisher: Dovetail Games - TSW - Released: 2026 · Genre: Simulation · List price: $49.99 - Deal grade: C (A = dormant with >=$5k/mo opportunity, D = low signal) - Est. net residual revenue: $24.0k to $36.0k per month (mid $30.0k) - Opportunity score: $30.0k/month at x1.00 dormancy multiplier - Est. lifetime owners: 3.1k · Est. lifetime net revenue: $51.6k - Review sentiment: 63% positive across 84 reviews (77 from Steam purchases) - Review velocity: 71.5 reviews/month (6-month average) ## Why it's flagged - Developer active, last post 0 months ago - Studio active elsewhere (11 titles tracked), so this one may welcome a partner ## Where a gross dollar goes (monthly, at current velocity) | Stage | USD/month | |---|---| | Gross storefront sales | $54.5k | | After VAT / sales tax (-13% blended) | $47.4k | | After refunds (-9.5% median) | $42.9k | | Net to developer (after Steam 30%) | $30.0k | ## Markets by review language - french: 1% - german: 32% - english: 49% - russian: 6% - schinese: 12% (game NOT localized in this language) Localization gap: 12% of measured reviews are written in languages the game does not support (top: schinese). 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.
