## Analyst notes (AI-assisted)

A 2020 remaster of KOEI TECMO's 2011 time-management alchemy RPG, part of the long-running Atelier franchise.

Atelier Ayesha DX sits in a profitable niche: a B-tier, 92%-positive catalog title generating $1.2k/mo residual revenue on minimal ongoing support. The franchise has a dedicated global fanbase and the remaster format suggests IP is owned by the publisher. For a publisher or platform seeking backlist catalog depth, or a revival partner targeting JRPG enthusiasts, this is a quiet earner worth monitoring, though the small player sample and thin review dataset limit confidence in community sentiment.

- Most realistic play: publishing
- Risk (market): Niche genre appeal; 15.6k lifetime units suggests a ceiling on addressable audience without major marketing spend or franchise-wide campaign.
- Risk (other): Developer has not posted in 31 months; zero commercial activity in 0.3 months is too recent to confirm abandonment, but long silent periods are typical for catalog titles.

Suggested first moves:
1. Audit full review corpus (558 total) for recurring feature requests (e.g., QoL, sequel interest, platform ports) to scope a revival or sequel case.
2. Verify KOEI TECMO's appetite to support a catalog refresh campaign; 8 promotions in 12 months and recent 60% max discount indicate active merchandising, not abandonment.
3. Model bundle or franchise bundle opportunity: Atelier Ayesha DX as a gateway to the broader Atelier catalog (which KOEI TECMO controls), especially if other dormant entries in the series show similar residual margins.

## 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.
