# Border Dungeon 边境地牢

- Steam appid: 3011740
- Developer: 清友工作室
- Released: 2024 · Genre: Casual · List price: $5.99
- Deal grade: B (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $198 to $298 per month (mid $248)
- Opportunity score: $471/month at x1.90 dormancy multiplier
- Est. lifetime owners: 1.0k · Est. lifetime net revenue: $1.8k
- Review sentiment: 70% positive across 37 reviews (32 from Steam purchases)
- Review velocity: 5.7 reviews/month (6-month average)

## Why it's flagged

- Developer silent for 2.2 years
- Studio active elsewhere (3 titles tracked), so this one may welcome a partner
- Last build shipped 26 months ago
- Store page localized in only 2 language(s)

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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $450 |
| After VAT / sales tax (-13% blended) | $392 |
| After refunds (-9.5% median) | $355 |
| Net to developer (after Steam 30%) | $248 |

## Monthly review counts, oldest to newest (6 months)

24, 6, 1, 1, 1, 1

## Estimated acquisition range

$6.0k to $11.9k (2-4x the trailing net annuity of $3.0k/year). Same error range applies.

## Markets by review language

- english: 19%
- russian: 3% (game NOT localized in this language)
- schinese: 77% (game NOT localized in this language)

Localization gap: 81% 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.
