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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $973 |
| After VAT / sales tax (-13% blended) | $847 |
| After refunds (-9.5% median) | $766 |
| Net to developer (after Steam 30%) | $536 |

## Monthly review counts, oldest to newest (8 months)

35, 7, 2, 2, 4, 1, 6, 9

## Markets by review language

- schinese: 74%
- english: 7%
- koreana: 18% (game NOT localized in this language)
- russian: 2% (game NOT localized in this language)

Localization gap: 19% 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.
