# Mecha Harem: Bonds of the Abyss

> ResidualPlay case file: an overlooked Steam game still earning residual revenue. Estimates carry a ±30-50% error range per title.

- Steam appid: 3949900
- Developer: YYGames
- Publisher: Morexingame
- Released: 2026 · Genre: Action · List price: $9.99
- Deal grade: D (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $442 to $663 per month (mid $553)
- Opportunity score: $553/month at x1.00 dormancy multiplier
- Est. lifetime owners: 1.1k · Est. lifetime net revenue: $3.6k
- Review sentiment: 88% positive across 75 reviews (34 from Steam purchases)
- Review velocity: 6.6 reviews/month (6-month average)

## Why it's flagged

- Developer active, last post 0 months ago
- Studio active elsewhere (2 titles tracked), so this one may welcome a partner
- Last build shipped 7 months ago
- 55% of reviews come from key activations (excluded from revenue estimates)
- Store page localized in only 4 language(s)
- Last discounted 1 months ago, 4 sales in the last 12 months

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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $1.0k |
| After VAT / sales tax (-13% blended) | $873 |
| After refunds (-9.5% median) | $790 |
| Net to developer (after Steam 30%) | $553 |

## Monthly review counts, oldest to newest (5 months)

8, 16, 8, 1, 0

## Missed seasonal-sale revenue (modeled)

Skipped 2 Steam seasonal sale window(s) in the last 5 months. Running a -50% discount in those windows is modeled at +$377 net in total, assuming a unit uplift of x3.0 (industry-typical for old catalog titles). Same ±30-50% error range applies.

## Markets by review language

- english: 12%
- russian: 12% (game NOT localized in this language)
- japanese: 6%
- schinese: 71%

Localization gap: 12% 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.
