## Markets by review language

- japanese: 7%
- schinese: 37%
- english: 41%
- koreana: 11% (game NOT localized in this language)
- russian: 4% (game NOT localized in this language)

Localization gap: 15% 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.
