# FATAL FRAME / PROJECT ZERO: Maiden of Black Water

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

- Steam appid: 1732190
- Developer: KOEI TECMO GAMES CO., LTD.
- Released: 2021 · Genre: Adventure · List price: $39.99
- Deal grade: A (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $8.3k to $12.5k per month (mid $10.4k)
- Opportunity score: $15.6k/month at x1.50 dormancy multiplier
- Est. lifetime owners: 173.6k · Est. lifetime net revenue: $1.7M
- Review sentiment: 83% positive across 6515 reviews (5426 from Steam purchases)
- Review velocity: 41.8 reviews/month (6-month average)

## Why it's flagged

- Developer active, last post 4 months ago
- Studio active elsewhere (76 titles tracked), so this one may welcome a partner
- Last build shipped 4.0 years ago
- Last discounted 1 months ago, 6 sales in the last 12 months

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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $18.9k |
| After VAT / sales tax (-13% blended) | $16.5k |
| After refunds (-9.5% median) | $14.9k |
| Net to developer (after Steam 30%) | $10.4k |

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

26, 30, 47, 26, 38, 31, 35, 32, 18, 23, 49, 30, 23, 54, 57, 34, 42, 46, 51, 64, 34, 39, 31, 32

## Missed seasonal-sale revenue (modeled)

Skipped 5 Steam seasonal sale window(s) in the last 24 months. Running a -50% discount in those windows is modeled at +$20.9k 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

$250.3k to $500.5k (2-4x the trailing net annuity of $125.1k/year). Same error range applies.

## Markets by review language

- english: 29%
- schinese: 53%
- koreana: 1% (game NOT localized in this language)
- russian: 2% (game NOT localized in this language)
- spanish: 3% (game NOT localized in this language)
- japanese: 5% (game NOT localized in this language)
- brazilian: 5% (game NOT localized in this language)
- french: 1%
- german: 1%

Localization gap: 16% of measured reviews are written in languages the game does not support (top: brazilian). Localizing is likely immediate market expansion.

## Analyst notes (AI-assisted)

Fatal Frame: Maiden of Black Water is a supernatural horror adventure where players photograph ghosts to survive, rebuilt for modern platforms in 2021.

Maiden of Black Water has accumulated $1.73M lifetime revenue on modest 173k units sold, with 82.7% positive reviews and $10.4k/mo residual earnings across PC, Switch and console ports. The franchise remains under Koei Tecmo's full control with no licensing complications, but the title is quiet on marketing despite strong critical reception and player demand for more remakes. This is a publishing opportunity for aggressive regional localization (16% gap in Brazilian Portuguese) and a revival candidate for franchise veterans interested in the back-catalog upside of a beloved IP that generates steady engagement without blockbuster sales infrastructure.

- Most realistic play: publishing
- Risk (market): Horror and supernatural adventure remain niche on PC; mainstream audience growth may plateau without significant marketing spend or franchise event tie-ins.
- Risk (tech): Player feedback on PC controls and fullscreen bugs suggests optimization gaps that could suppress conversion from keyboard-only users.
- Risk (other): No developer communication for 4+ months; unclear if Koei Tecmo is prioritizing additional content, ports, or moving resources elsewhere.

What players are asking for:
- Remake or remaster the earlier Fatal Frame 1 and 2 titles for modern platforms
- Fix PC keyboard and fullscreen mode issues
- Expand localization to underserved regions (Brazilian Portuguese, others)
- More frequent seasonal content or DLC to sustain engagement

Suggested first moves:
1. Audit and patch PC controls/fullscreen rendering; identify quick wins to convert the keyboard-averse segment.
2. Commission Brazilian Portuguese localization and test regional pricing; the 16% loc gap and 226 Brazilian reviews suggest untapped revenue in LatAm.
3. Partner with Koei Tecmo on a 12-month roadmap announcement: seasonal cosmetics, story DLC, or spin-off titles to sustain $10k+/mo and signal active stewardship to the franchise fanbase.

## 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.
