## Missed seasonal-sale revenue (modeled)

Skipped 2 Steam seasonal sale window(s) in the last 19 months. Running a -50% discount in those windows is modeled at +$6.9k net in total, assuming a unit uplift of x3.0 (industry-typical for old catalog titles). Same ±30-50% error range applies.

## Markets by review language

- japanese: 2%
- schinese: 12%
- brazilian: 5%
- french: 2%
- german: 6%
- english: 64%
- russian: 5% (game NOT localized in this language)
- spanish: 2%
- koreana: 3%

## 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.
