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

- Steam appid: 3481320
- Developer: Room Games
- Released: 2025 · Genre: Action · List price: $3.99
- Deal grade: B (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $192 to $288 per month (mid $240)
- Opportunity score: $324/month at x1.35 dormancy multiplier

## Why it's flagged

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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $435 |
| After VAT / sales tax (-13% blended) | $379 |
| After refunds (-9.5% median) | $343 |
| Net to developer (after Steam 30%) | $240 |

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

164, 13, 10, 7, 10, 12, 26, 5, 3, 5, 5, 24, 2, 1, 6

## Missed seasonal-sale revenue (modeled)

Skipped 3 Steam seasonal sale window(s) in the last 15 months. Running a -50% discount in those windows is modeled at +$819 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

$5.8k to $11.5k (2-4x the trailing net annuity of $2.9k/year). Same error range applies.

## Markets by review language

- german: 1%
- english: 34%
- russian: 61%
- japanese: 1%
- brazilian: 1%
- french: 0%
- koreana: 1%
- spanish: 1% (game NOT localized in this language)
- schinese: 1%

## 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.
