- Publisher: XD
- Released: 2025 · Genre: Adventure · List price: $14.99
- Deal grade: B (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $419 to $628 per month (mid $524)

## Why it's flagged

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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $951 |
| After VAT / sales tax (-13% blended) | $827 |
| After refunds (-9.5% median) | $748 |
| Net to developer (after Steam 30%) | $524 |

## Monthly review counts, oldest to newest (9 months)

154, 14, 5, 7, 6, 3, 5, 1, 3

## Estimated acquisition range

$12.6k to $25.1k (2-4x the trailing net annuity of $6.3k/year). Same error range applies.

## Markets by review language

- english: 10% (game NOT localized in this language)
- russian: 1% (game NOT localized in this language)
- spanish: 1% (game NOT localized in this language)
- japanese: 2%
- schinese: 86%
- german: 1% (game NOT localized in this language)

Localization gap: 12% of measured reviews are written in languages the game does not support (top: english). 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.
