# Saiko no sutoka

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

- Steam appid: 1546860
- Developer: Habupain
- Released: 2021 · Genre: Action · List price: $4.99
- Deal grade: B (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $883 to $1.3k per month (mid $1.1k)
- Opportunity score: $2.3k/month at x2.10 dormancy multiplier
- Est. lifetime owners: 114.4k · Est. lifetime net revenue: $142.3k
- Review sentiment: 92% positive across 3848 reviews (3574 from Steam purchases)
- Review velocity: 35.5 reviews/month (6-month average)

## Why it's flagged

- Developer silent for 4.9 years
- Studio quiet across its whole catalog
- Last build shipped 4.9 years ago
- Last discounted 5 months ago, 6 sales in the last 12 months

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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $2.0k |
| After VAT / sales tax (-13% blended) | $1.7k |
| After refunds (-9.5% median) | $1.6k |
| Net to developer (after Steam 30%) | $1.1k |

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

53, 28, 40, 31, 51, 35, 25, 43, 33, 32, 36, 39, 31, 29, 30, 32, 34, 38, 32, 36, 33, 42, 30, 40

## Missed seasonal-sale revenue (modeled)

Skipped 7 Steam seasonal sale window(s) in the last 24 months. Running a -50% discount in those windows is modeled at +$3.8k 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

$26.5k to $53.0k (2-4x the trailing net annuity of $13.3k/year). Same error range applies.

## Markets by review language

- french: 3%
- english: 42%
- russian: 21%
- japanese: 1%
- german: 2%
- koreana: 5%
- spanish: 7%
- schinese: 14% (game NOT localized in this language)
- brazilian: 5%

Localization gap: 14% of measured reviews are written in languages the game does not support (top: schinese). Localizing is likely immediate market expansion.

## Analyst notes (AI-assisted)

A 2021 Japanese-style horror-action game with aggressive AI and high difficulty, earning residual revenue across 12 languages with strong community passion despite developer inactivity.

Saiko no Sutoka has generated $142k lifetime on a $4.99 price point with 91.6% positive reviews and stable $1.1k/mo residual earnings, despite no developer communication in 58 months. The title shows genuine community attachment (35.5 reviews/mo) and untapped localization potential (14% gap to Simplified Chinese), making it a candidate for publishing takeover, language expansion, or console porting rather than acquisition. Dormancy is a feature here, not a bug: the game runs profitably on autopilot.

- Most realistic play: publishing
- Risk (tech): 58-month radio silence from developer raises questions about ongoing platform parity, anti-cheat, or engine maintenance as OS updates accumulate.
- Risk (market): Niche horror-action positioning limits upside; elasticity of 1.05 suggests minimal pricing room and discount fatigue (last deep sale 4.9 months ago).
- Risk (other): Solo-title studio with 'ghost' status signals zero institutional knowledge; any revival requires external expertise.

What players are asking for:
- Remake or expanded sequel addressing difficulty balance and bug fixes
- Simplified Chinese localization (noted as largest language gap)
- Active post-launch support or clarification on project status

Suggested first moves:
1. Audit code and platforms (Windows, macOS, Proton) for critical regressions; budget a small QA pass if parity is broken.
2. Expand Simplified Chinese UI/text (14% localization gap represents ~$300-500/mo opportunity given Korean and Russian traction).
3. Contact Habupain via all known channels (email, social) to acquire rights or at minimum secure a blessing for minor patches; if unreachable after 60 days, consult IP counsel on dormant-developer provisions in Steam terms.

## 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.
