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

- Steam appid: 3625270
- Developer: Shinyflvres
- Publisher: Shinymoon
- Released: 2025 · Genre: Animation & Modeling · List price: $5.49
- Deal grade: C (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $1.5k to $2.3k per month (mid $1.9k)
- Opportunity score: $1.9k/month at x1.00 dormancy multiplier
- Est. lifetime owners: 30.4k · Est. lifetime net revenue: $56.0k
- Review sentiment: 97% positive across 994 reviews (950 from Steam purchases)

## Why it's flagged

- Developer active, last post 7 months ago
- Last build shipped 7 months ago

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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $3.5k |
| After VAT / sales tax (-13% blended) | $3.0k |
| After refunds (-9.5% median) | $2.7k |
| Net to developer (after Steam 30%) | $1.9k |

## Monthly review counts, oldest to newest (16 months)

106, 151, 53, 42, 32, 28, 97, 65, 83, 68, 48, 51, 41, 28, 38, 43

## Missed seasonal-sale revenue (modeled)

Skipped 8 Steam seasonal sale window(s) in the last 16 months. Running a -50% discount in those windows is modeled at +$10.2k net in total, assuming a unit uplift of x3.0 (industry-typical for old catalog titles). Same ±30-50% error range applies.

## Markets by review language

- english: 56%
- koreana: 3%
- russian: 9%
- spanish: 3%
- japanese: 3%
- schinese: 22% (game NOT localized in this language)
- brazilian: 1% (game NOT localized in this language)
- french: 1%
- german: 2%

Localization gap: 23% 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.
