## Monthly review counts, oldest to newest (22 months)

## Markets by review language

- english: 75%
- koreana: 1% (game NOT localized in this language)
- russian: 11% (game NOT localized in this language)
- spanish: 4% (game NOT localized in this language)
- french: 1%
- german: 1%

- schinese: 2% (game NOT localized in this language)

## 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.
