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

- Steam appid: 2405360
- Developer: 艾斯尼斯
- Released: 2025 · Genre: Adventure · List price: $1.99
- Deal grade: D (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $440 to $661 per month (mid $551)
- Opportunity score: $688/month at x1.25 dormancy multiplier
- Est. lifetime owners: 4.1k · Est. lifetime net revenue: $2.8k
- Review sentiment: 88% positive across 130 reviews (129 from Steam purchases)
- Review velocity: 33.0 reviews/month (6-month average)

## Why it's flagged

- Developer active, last post 7 months ago
- Last build shipped 6 months ago
- Store page localized in only 1 language(s)
- Last discounted 9 months ago, 4 sales in the last 12 months

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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $999 |
| After VAT / sales tax (-13% blended) | $869 |
| After refunds (-9.5% median) | $787 |
| Net to developer (after Steam 30%) | $551 |

## Monthly review counts, oldest to newest (4 months)

123, 4, 2, 3

## Missed seasonal-sale revenue (modeled)

Skipped 1 Steam seasonal sale window(s) in the last 4 months. Running a -50% discount in those windows is modeled at +$25 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

- 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 (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.
