## Analyst notes (AI-assisted)

A 2015 otome visual novel where an amnesiac protagonist navigates romance routes with five male characters, each with distinct personality archetypes and story branches.

Amnesia: Memories remains a canonical entry point for the otome genre, with 92.6% positive reviews and steady $3,230/mo residual revenue nine years post-launch. The game's dormant but engaged community continues replaying and recommending it, particularly to newcomers. For publishers seeking catalog depth in the visual-novel space or indie studios exploring genre licensing, this title offers stable, low-maintenance royalty income with minimal platform risk.

- Most realistic play: watch
- Risk (market): Otome genre has expanded significantly since 2015; newer, higher-production titles compete for mindshare and may cannibalize legacy sales.
- Risk (tech): Engine and UI are 10+ years old; porting to new platforms or modernizing would require substantial engineering investment.
- Risk (other): Protagonist's lack of agency and characterization is a recurring friction point; story structure limits appeal beyond core otome fans.

What players are asking for:
- Extended or alternate routes with deeper character development (especially for Toma, Ukyo)
- Improved protagonist characterization and agency
- Modern port/remaster for console or mobile platforms

Suggested first moves:
1. Audit Idea Factory International's current rights holder status and publishing renewal terms; confirm whether Amnesia IP is owned outright or subject to co-publishing agreements.
2. Model console port economics (Nintendo Switch, PlayStation) targeting otome-adjacent markets (Japan, Southeast Asia); review platform parity and localization cost against $3,230/mo current residual.
3. Commission a lightweight community survey via Steam announcement or Discord to validate appetite for a character episode DLC (Toma/Ukyo deep-dive) as a near-term revenue catalyst without full remake investment.

## 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.
