Best ForInvestigation-driven horror where combat is deadly and sanity is fragile. Great for one-shots.Groups who want episodic monster-hunting adventures inspired by Buffy, Supernatural, and The X-Files — investigating mysteries, confronting creatures, and dealing with hunter drama.
HighlightsSanity system mechanically reinforces horror tone. Intuitive percentile skill system with tiered success levels. One of the largest published scenario libraries in the hobby.Very easy to learn, mystery countdown gives the Keeper a clear prep framework, playbooks map directly to genre archetypes
ConsiderationsChase rules add complexity with limited payoff, 46-skill list requires point allocation across multiple categories, sanity spiral can remove player agency in extended campaignsNo pre-written mysteries in the core book, limited mechanical depth for long campaigns, custom move design requires GM experience, monster creation guidelines are loose
