## Analyst notes (AI-assisted)

Evil Nun: The Broken Mask is a first-person horror action game centered on escaping from a possessed nun in an eerie school setting.

The title sits in a quiet pocket, generating $1.5k/mo in residual revenue on a $20 price point with 95% positive reviews and modest but steady engagement (12 reviews/month). Studio appears fading with only one title, no discounts ever applied, and no developer communication in 19 months, suggesting either hands-off monetization or dormancy. For a small publisher or revival-focused studio, the IP and positive community sentiment represent low-risk catalog acquisition potential, though the absence of recent updates or sales velocity in the past year warrants investigation into why a well-reviewed title isn't being actively supported.

- Most realistic play: acquisition
- Risk (other): Studio marked 'fading' with single-title portfolio and 19-month radio silence; ownership or operational continuity unclear.
- Risk (market): Zero sales tracked in past 12 months despite positive reviews, suggesting either data blindness or genuine sales stall that no-discount strategy has not reversed.
- Risk (tech): Built 31 months ago; no meaningful updates documented, risking engine/dependency rot and platform certification drift.

Suggested first moves:
1. Verify current ownership and developer contact status; confirm whether Keplerians is still operating or if IP/rights are entangled.
2. Audit the game's backend (multiplayer servers, third-party SDKs, licensing dependencies) to confirm technical acquisition feasibility and ongoing support cost.
3. Analyze 12-month sales cliff: determine if it reflects platform algorithm change, lack of marketing, or organic audience saturation, then model modest revival spend (sale, update, community outreach) against projected payback period.

## 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.
