- Steam appid: 1848270
- Developer: Sins of Succubus
- Publisher: Mango Party
- Released: 2024 · Genre: Indie · List price: $7.99
- Deal grade: B (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $374 to $561 per month (mid $467)
- Opportunity score: $888/month at x1.90 dormancy multiplier
- Est. lifetime owners: 15.1k · Est. lifetime net revenue: $35.4k
- Review sentiment: 83% positive across 518 reviews (473 from Steam purchases)
- Review velocity: 8.0 reviews/month (6-month average)

## Why it's flagged

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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $848 |
| After VAT / sales tax (-13% blended) | $738 |
| After refunds (-9.5% median) | $668 |
| Net to developer (after Steam 30%) | $467 |

## Monthly review counts, oldest to newest (24 months)

12, 15, 10, 16, 17, 8, 4, 6, 4, 2, 9, 4, 2, 8, 10, 8, 3, 4, 11, 7, 9, 5, 9, 7

## Missed seasonal-sale revenue (modeled)

Skipped 3 Steam seasonal sale window(s) in the last 24 months. Running a -50% discount in those windows is modeled at +$817 net in total, assuming a unit uplift of x3.0 (industry-typical for old catalog titles). Same ±30-50% error range applies.

## Estimated acquisition range

$11.2k to $22.4k (2-4x the trailing net annuity of $5.6k/year). Same error range applies.

## Markets by review language

- koreana: 19%
- russian: 7% (game NOT localized in this language)
- japanese: 2%
- schinese: 28%
- brazilian: 1% (game NOT localized in this language)
- french: 1% (game NOT localized in this language)
- german: 1% (game NOT localized in this language)
- english: 39%
- spanish: 1% (game NOT localized in this language)

Localization gap: 11% of measured reviews are written in languages the game does not support (top: russian). 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.
