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

- Steam appid: 1806330
- Developer: Edanoue, Inc.
- Released: 2025 · Genre: Adventure · List price: $11.99
- Deal grade: B (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $523 to $784 per month (mid $653)
- Opportunity score: $882/month at x1.35 dormancy multiplier
- Est. lifetime owners: 9.5k · Est. lifetime net revenue: $38.3k
- Review sentiment: 95% positive across 306 reviews (298 from Steam purchases)
- Review velocity: 6.5 reviews/month (6-month average)

## Why it's flagged

- Developer silent for 12 months
- Last build shipped 12 months ago
- Store page localized in only 2 language(s)
- Last discounted 1 months ago, 4 sales in the last 12 months

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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $1.2k |
| After VAT / sales tax (-13% blended) | $1.0k |
| After refunds (-9.5% median) | $934 |
| Net to developer (after Steam 30%) | $653 |

## Monthly review counts, oldest to newest (12 months)

201, 13, 22, 10, 8, 11, 8, 13, 5, 7, 2, 4

## Missed seasonal-sale revenue (modeled)

Skipped 4 Steam seasonal sale window(s) in the last 12 months. Running a -50% discount in those windows is modeled at +$2.1k 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

$15.7k to $31.4k (2-4x the trailing net annuity of $7.8k/year). Same error range applies.

## Markets by review language

- english: 2% (game NOT localized in this language)
- koreana: 4% (game NOT localized in this language)
- japanese: 47%
- schinese: 47%

## 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.
