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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $989 |
| After VAT / sales tax (-13% blended) | $860 |
| After refunds (-9.5% median) | $779 |
| Net to developer (after Steam 30%) | $545 |

## Monthly review counts, oldest to newest (16 months)

87, 3, 1, 3, 3, 2, 1, 2, 2, 3, 1, 3, 6, 1, 1, 1

## Estimated acquisition range

$13.1k to $26.1k (2-4x the trailing net annuity of $6.5k/year). Same error range applies.

## Markets by review language

- russian: 4% (game NOT localized in this language)
- japanese: 22%
- schinese: 42%
- french: 1% (game NOT localized in this language)
- german: 1% (game NOT localized in this language)
- english: 25%
- koreana: 5% (game NOT localized in this language)

Localization gap: 12% of measured reviews are written in languages the game does not support (top: koreana). 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.
