# Ile d'Or

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

- Steam appid: 3561770
- Developer: あとらそふと
- Released: 2025 · Genre: Adventure · List price: $14.99
- Deal grade: D (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $402 to $603 per month (mid $503)
- Opportunity score: $503/month at x1.00 dormancy multiplier
- Est. lifetime owners: 5.2k · Est. lifetime net revenue: $26.2k
- Review sentiment: 89% positive across 164 reviews (163 from Steam purchases)
- Review velocity: 4.0 reviews/month (6-month average)

## Why it's flagged

- Developer active, last post 0 months ago
- Last build shipped 1 months ago
- Store page localized in only 1 language(s)
- Last discounted 1 months ago, 5 sales in the last 12 months

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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $912 |
| After VAT / sales tax (-13% blended) | $794 |
| After refunds (-9.5% median) | $718 |
| Net to developer (after Steam 30%) | $503 |

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

24, 33, 15, 20, 22, 8, 4, 4, 2, 6, 5, 2, 7, 4, 3, 3

## Missed seasonal-sale revenue (modeled)

Skipped 5 Steam seasonal sale window(s) in the last 16 months. Running a -50% discount in those windows is modeled at +$2.6k 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: 1% (game NOT localized in this language)
- koreana: 3% (game NOT localized in this language)
- japanese: 74%
- schinese: 22% (game NOT localized in this language)

Localization gap: 26% 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.
