## Monthly review counts, oldest to newest (17 months)

## Missed seasonal-sale revenue (modeled)

Skipped 1 Steam seasonal sale window(s) in the last 17 months. Running a -50% discount in those windows is modeled at +$754 net in total, assuming a unit uplift of x3.0 (industry-typical for old catalog titles). Same ±30-50% error range applies.

## Estimated acquisition range

$8.0k to $16.1k (2-4x the trailing net annuity of $4.0k/year). Same error range applies.

## Markets by review language

- english: 14%
- koreana: 72%
- russian: 2%
- spanish: 1%
- japanese: 4%
- schinese: 3%
- french: 2%
- german: 2%

## 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.
