## Analyst notes (AI-assisted)

A 2018 prequel visual novel by NOVECT that expands the narrative of The House in Fata Morgana by reframing its tragedy from a new perspective.

A Requiem for Innocence sits in a rare position: a dormant but consistently praised addon to a cult visual novel with 97% positive reviews and steady monthly traction ($2,739/mo residual). The title generates modest revenue at $14.99 with no discounting strategy, suggesting price elasticity and market underexposure rather than audience fatigue. For publishers seeking to acquire backlist visual-novel IP or revival partners looking to bundle and remarket the full House in Fata Morgana series to a widening anime-adjacent audience, this title's cult status and devotion (avg 21 hours per player) indicate untapped upside.

- Most realistic play: publishing
- Risk (market): Prequel dependency: acquisition value depends critically on owning or licensing the base game; standalone sales appear negligible.
- Risk (other): Developer silent 34 months; no update or engagement signals may signal waning capacity to support or localize further content.
- Risk (tech): Visual novel engine and asset legacy unknown; porting or live-service expansion may require substantial remake investment.

What players are asking for:
- English/localization improvements or official translations for remaining languages
- Physical release or bundled collection of both games
- Character epilogue or bonus story content exploring Jacopo's aftermath

Suggested first moves:
1. Audit IP ownership and localization rights held by NOVECT and MangaGamer; confirm optionality on both base and prequel titles as a bundled package.
2. Model revenue uplift from a modern Steam discovery refresh (store tags, community hub activation, seasonal discount) and from a console port or GOG release; prequel dependency suggests bundle-with-base strategy.
3. Engage NOVECT on current studio capacity and interest in a remaster, behind-the-scenes artbook, or narrative DLC; 34-month silence may reflect resource constraints rather than disinterest in franchise.

## 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.
