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

- Steam appid: 2867460
- Developer: NineDay
- Publisher: Mango Party
- Released: 2025 · Genre: Casual · List price: $10.99
- Deal grade: D (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $602 to $903 per month (mid $752)
- Opportunity score: $752/month at x1.00 dormancy multiplier
- Est. lifetime owners: 16.4k · Est. lifetime net revenue: $60.5k
- Review sentiment: 87% positive across 558 reviews (513 from Steam purchases)
- Review velocity: 8.2 reviews/month (6-month average)

## Why it's flagged

- Developer active, last post 6 months ago
- Last build shipped 15 months ago
- Last discounted 1 months ago, 8 sales in the last 12 months

## 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%) | $752 |

## Monthly review counts, oldest to newest (15 months)

299, 55, 25, 19, 16, 17, 27, 11, 17, 9, 5, 5, 9, 11, 10

## Missed seasonal-sale revenue (modeled)

Skipped 8 Steam seasonal sale window(s) in the last 15 months. Running a -50% discount in those windows is modeled at +$7.4k 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

- spanish: 2% (game NOT localized in this language)
- japanese: 2%
- schinese: 44%
- brazilian: 0% (game NOT localized in this language)
- french: 1% (game NOT localized in this language)
- english: 22%
- koreana: 24% (game NOT localized in this language)
- russian: 6% (game NOT localized in this language)

Localization gap: 33% of measured reviews are written in languages the game does not support (top: koreana). 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.
