| Gross storefront sales | $962 |

## Markets by review language

- french: 7% (game NOT localized in this language)
- german: 17% (game NOT localized in this language)
- english: 76%

Localization gap: 24% of measured reviews are written in languages the game does not support (top: german). 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.
