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.
HighlightsTracking Sanity as a depletable score ties mental erosion to the fiction, so confronting cosmic horror mechanically wears characters down. The percentile skills resolve on a d100 roll-under, with Hard and Extreme bands at half and one-fifth of the rating. Bouts of Madness convert failed Sanity checks into temporary phobias, manias, or loss of character control.Tag system makes every character unique, investigation mechanics are well-designed, layered interplay between mythic and mundane identity
ConsiderationsThe chase rules add a detailed positioning subsystem whose complexity outweighs how often it sees use. Character creation allocates points across a long list of skills, a slow first step for new players. In long campaigns the sanity spiral can strip a character of player control as madness accumulates.Tag-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
