| Gross storefront sales | $1.2k |

## Markets by review language

- koreana: 8% (game NOT localized in this language)
- russian: 5% (game NOT localized in this language)
- spanish: 3% (game NOT localized in this language)
- schinese: 10% (game NOT localized in this language)
- english: 74%

Localization gap: 26% of measured reviews are written in languages the game does not support (top: schinese). 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.
