Best ForInvestigation-driven horror where combat is deadly and sanity is fragile. Great for one-shots.Groups who want noir-style investigations in a modern city where characters channel mythological archetypes — balancing mundane lives with legendary powers.
HighlightsSanity system mechanically reinforces horror tone. Intuitive percentile skill system with tiered success levels. One of the largest published scenario libraries in the hobby.Tag system makes every character unique, investigation mechanics are well-designed, layered interplay between mythic and mundane identity
ConsiderationsChase rules add complexity with limited payoff, 46-skill list requires point allocation across multiple categories, sanity spiral can remove player agency in extended campaignsTag-based resolution takes adjustment from traditional RPGs, heavily tied to its urban noir setting, two-book format can feel expensive, prep-intensive for the MC
