- Deal grade: D (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $354 to $531 per month (mid $443)
- Opportunity score: $443/month at x1.00 dormancy multiplier

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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $804 |
| After VAT / sales tax (-13% blended) | $699 |
| After refunds (-9.5% median) | $633 |
| Net to developer (after Steam 30%) | $443 |

## Monthly review counts, oldest to newest (22 months)

164, 28, 30, 21, 7, 7, 5, 4, 6, 3, 4, 4, 5, 3, 18, 22, 10, 8, 10, 5, 5, 14

## Missed seasonal-sale revenue (modeled)

Skipped 5 Steam seasonal sale window(s) in the last 22 months. Running a -50% discount in those windows is modeled at +$2.0k 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: 39%
- koreana: 1% (game NOT localized in this language)
- russian: 0% (game NOT localized in this language)
- japanese: 59%
- schinese: 0%
- brazilian: 1% (game NOT localized in this language)

## 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.
