|---|---|
| Gross storefront sales | $234 |

1, 3, 1, 2, 1, 4, 1, 1, 2, 1, 3, 1, 1, 1, 1, 1, 1, 1, 3, 3, 4, 1, 1, 0

## 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.
