# RUNNING TRAIN | 走ル列車！

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

- Steam appid: 4630570
- Developer: Novatetsu Games
- Released: 2026 · Genre: Casual · List price: $19.99
- Deal grade: A (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $64.4k to $96.7k per month (mid $80.5k)
- Opportunity score: $120.8k/month at x1.50 dormancy multiplier
- Est. lifetime owners: 47.7k · Est. lifetime net revenue: $319.6k
- Review sentiment: 98% positive across 1532 reviews (1490 from Steam purchases)
- Review velocity: 480.7 reviews/month (6-month average)

## Why it's flagged

- Developer active, last post 1 months ago
- Last build shipped 3 months ago
- Store page localized in only 2 language(s)
- 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 | $146.2k |
| After VAT / sales tax (-13% blended) | $127.2k |
| After refunds (-9.5% median) | $115.1k |
| Net to developer (after Steam 30%) | $80.5k |

## Monthly review counts, oldest to newest (3 months)

877, 376, 189

## Missed seasonal-sale revenue (modeled)

Skipped 2 Steam seasonal sale window(s) in the last 3 months. Running a -50% discount in those windows is modeled at +$47.3k net in total, assuming a unit uplift of x3.0 (industry-typical for old catalog titles). Same ±30-50% error range applies.

## Estimated acquisition range

$1.9M to $3.9M (2-4x the trailing net annuity of $966.6k/year). Same error range applies.

## Markets by review language

- german: 6% (game NOT localized in this language)
- koreana: 3% (game NOT localized in this language)
- russian: 4% (game NOT localized in this language)
- spanish: 2% (game NOT localized in this language)
- japanese: 10% (game NOT localized in this language)
- french: 4% (game NOT localized in this language)
- english: 59%
- schinese: 11% (game NOT localized in this language)
- brazilian: 1% (game NOT localized in this language)

Localization gap: 41% 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 (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.
