## Where a gross dollar goes (monthly, at current velocity)

| Stage | USD/month |
|---|---|
| Gross storefront sales | $1.1k |
| After VAT / sales tax (-13% blended) | $923 |
| After refunds (-9.5% median) | $835 |
| Net to developer (after Steam 30%) | $584 |

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

20, 6, 7, 2, 6, 2, 1, 1, 2, 3, 2, 3, 2, 3, 2, 3, 3

## Estimated acquisition range

$14.0k to $28.1k (2-4x the trailing net annuity of $7.0k/year). Same error range applies.

## Markets by review language

- english: 5% (game NOT localized in this language)
- koreana: 3% (game NOT localized in this language)
- japanese: 73%
- schinese: 20% (game NOT localized in this language)

Localization gap: 27% of measured reviews are written in languages the game does not support (top: schinese). 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.
