|---|---|
| Gross storefront sales | $862 |

## Missed seasonal-sale revenue (modeled)

Skipped 7 Steam seasonal sale window(s) in the last 14 months. Running a -50% discount in those windows is modeled at +$3.8k 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

$11.4k to $22.8k (2-4x the trailing net annuity of $5.7k/year). Same error range applies.

## Markets by review language

- english: 21%
- koreana: 42%
- russian: 2% (game NOT localized in this language)
- spanish: 4% (game NOT localized in this language)
- japanese: 9%
- schinese: 21%
- brazilian: 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.
