|---|---|
| Gross storefront sales | $1.4k |
| After VAT / sales tax (-13% blended) | $1.2k |
| After refunds (-9.5% median) | $1.1k |
| Net to developer (after Steam 30%) | $751 |

## Monthly review counts, oldest to newest (2 months)

55, 1

## Estimated acquisition range

$18.0k to $36.0k (2-4x the trailing net annuity of $9.0k/year). Same error range applies.

## Markets by review language

- english: 16%
- spanish: 82% (game NOT localized in this language)
- schinese: 2% (game NOT localized in this language)

Localization gap: 84% of measured reviews are written in languages the game does not support (top: spanish). 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.
