# The Wraith Train: Illusory Domain

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

**Measured on 2026-09-01 19:22 UTC.** The whole Steam catalog is re-measured daily; a game that just launched can move a lot between passes.

- Steam appid: 4920100
- Developer: 司命工作室
- Released: 2026 · Genre: Adventure · List price: $3.99
- Deal grade: B (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $629 to $944 per month (mid $787)
- Opportunity score: $1.5k/month at x1.90 dormancy multiplier
- Est. lifetime owners: 1.1k · Est. lifetime net revenue: $1.4k
- Review sentiment: 87% positive across 31 reviews (27 from Steam purchases)
- Review velocity: 23.5 reviews/month (6-month average)

## Why it's flagged

- No developer announcement on record, ever
- Last build shipped 0 months ago
- Store page localized in only 2 language(s)

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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $1.4k |
| After VAT / sales tax (-13% blended) | $1.2k |
| After refunds (-9.5% median) | $1.1k |
| Net to developer (after Steam 30%) | $787 |

## Estimated acquisition range

$18.9k to $37.8k (2-4x the trailing net annuity of $9.4k/year). Same error range applies.

## Markets by review language

- schinese: 100% (game NOT localized in this language)

Localization gap: 100% 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.
