A 2018 action-adventure spinoff in the Touhou Project universe, positioning itself as an accessible alternative to the franchise's bullet-hell norm.

Scarlet Curiosity holds steady residual revenue with a high positive-sentiment core (92% approval) despite minimal developer engagement over three years. The title occupies a narrow but defensible niche: Touhou fans seeking story and accessible combat over mechanical mastery. For a publisher, the opportunity lies in modest catalog rotation and seasonal discounting; for a licensor or revival candidate, the risk profile is modest but the upside is limited by the dormant developer and the property's licensing constraints. This is not a breakout play, but a reliable shelf title with modest monthly returns. Most realistic play: licensing.

Risk: Game is built on Touhou Project IP; rights likely held by ZUN (the original creator) or a licensed publisher; acquisition of this title alone does not grant independent franchise control.
Risk: Six-year-old codebase with no recent developer updates; modernization for newer platforms or engines would require substantial investment.
Risk: Peak monthly players currently in single digits; the active audience is small and may not sustain post-revival engagement without significant marketing or content refresh.
