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

- Steam appid: 2392280
- Developer: Blockage
- Released: 2025 · Genre: Adventure · List price: $17.99
- Deal grade: D (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $623 to $935 per month (mid $779)
- Opportunity score: $779/month at x1.00 dormancy multiplier
- Est. lifetime owners: 10.0k · Est. lifetime net revenue: $60.0k
- Review sentiment: 81% positive across 369 reviews (311 from Steam purchases)
- Review velocity: 5.2 reviews/month (6-month average)

## Why it's flagged

- Proven demand elasticity: x2.5 review velocity during past deep sales

## 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%) | $779 |

## Monthly review counts, oldest to newest (23 months)

54, 10, 6, 15, 14, 7, 13, 7, 9, 64, 31, 24, 9, 2, 5, 9, 7, 6, 4, 8, 8, 2, 3

## Missed seasonal-sale revenue (modeled)

Skipped 3 Steam seasonal sale window(s) in the last 23 months. Running a -50% discount in those windows is modeled at +$985 net in total, assuming a unit uplift of x2.5 taken from this game's own sale history. Same ±30-50% error range applies.

## Markets by review language

- french: 2%
- german: 1%
- english: 79%
- koreana: 6%
- spanish: 1%
- schinese: 5%
- brazilian: 1%
- russian: 3%
- japanese: 2%

## 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.
