| Stage | USD/month |
|---|---|
| Gross storefront sales | $4.7k |

## Monthly review counts, oldest to newest (6 months)

142, 16, 3, 9, 11, 4

## Missed seasonal-sale revenue (modeled)

Skipped 3 Steam seasonal sale window(s) in the last 6 months. Running a -50% discount in those windows is modeled at +$1.3k 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

- english: 21%
- koreana: 6% (game NOT localized in this language)
- russian: 6%
- japanese: 16%
- schinese: 50%
- french: 1% (game NOT localized in this language)
- german: 1% (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.
