| After refunds (-9.5% median) | $818 |
| Net to developer (after Steam 30%) | $572 |

## Monthly review counts, oldest to newest (7 months)

81, 12, 6, 5, 5, 9, 4

## Estimated acquisition range

$13.7k to $27.5k (2-4x the trailing net annuity of $6.9k/year). Same error range applies.

## Markets by review language

- brazilian: 1% (game NOT localized in this language)
- english: 37%
- koreana: 9% (game NOT localized in this language)
- russian: 10% (game NOT localized in this language)
- spanish: 4% (game NOT localized in this language)
- japanese: 5%
- schinese: 34%

Localization gap: 24% of measured reviews are written in languages the game does not support (top: russian). Localizing is likely immediate market expansion.

## 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.
