Touhou 17, a 2019 bullet-hell shmup by ZUN's circle, featuring animal spirit mechanics and playable Youmu across three difficulty routes.

This entry holds steady residual revenue with minimal promotional overhead and maintains exceptionally high review sentiment despite a three-year dormancy. The franchise's devoted, multilingual fanbase (especially Chinese speakers) continues to engage; however, the property's status as fan-created derivative work built atop indie roots creates acquisition complexity. Most relevant for publishers already embedded in Touhou licensing or revival teams confident in the franchise's catalog evergreen appeal. Most realistic play: licensing.

• Risk: Franchise appeal is narrow and highly niche; mainstream audience discovery is limited by genre and cultural specificity.
• Risk: No recent developer engagement (months_since_dev_post unknown; sales_12m shows zero discount runs); engine and compatibility drift risk over time.
• Risk: Localization gap of 93% in simplified Chinese suggests untapped market, but monetization upside may be constrained by regional licensing complexity.
