> ResidualPlay case file: an overlooked Steam game still earning residual revenue. Estimates carry a ±30-50% error range per title.

- Steam appid: 3890400
- Developer: BKM
- Released: 2025 · Genre: Simulation · List price: $8.99
- Deal grade: D (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $251 to $377 per month (mid $314)
- Opportunity score: $314/month at x1.00 dormancy multiplier
- Est. lifetime owners: 3.7k · Est. lifetime net revenue: $11.3k
- Review sentiment: 97% positive across 118 reviews (117 from Steam purchases)
- Review velocity: 4.2 reviews/month (6-month average)

## Why it's flagged

## Where a gross dollar goes (monthly, at current velocity)

| Stage | USD/month |
|---|---|
| Gross storefront sales | $570 |
| After VAT / sales tax (-13% blended) | $496 |
| After refunds (-9.5% median) | $449 |
| Net to developer (after Steam 30%) | $314 |

## Monthly review counts, oldest to newest (10 months)

34, 28, 14, 15, 0, 6, 8, 7, 1, 3

## Markets by review language

- german: 91% (game NOT localized in this language)
- english: 9%

Localization gap: 91% of measured reviews are written in languages the game does not support (top: german). Localizing is likely immediate market expansion.

## Methodology

Units are estimated from Steam-purchase reviews times a release-cohort multiplier (Boxleiter method, 20-75x by year). 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.
