Best ForGMs who want to build a custom system from modular parts — homebrew designers, genre-mixers, and groups tired of forcing their stories into a pre-built framework.Narrative-focused groups who want to tell collaborative stories in any genre with minimal rules.
HighlightsHighly modular — 18+ mods for core rules alone, clear writing with worked examples, Plot Point economy creates dynamic give-and-take, powered well-known licensed games (Marvel Heroic, Firefly, Leverage)Genre-agnostic, encourages narrative play, free rules
ConsiderationsNot playable out of the box — requires significant GM assembly, steep learning curve to understand which mods fit your game, less community content than Fate or GURPS, restricted third-party publishing ecosystemAspect economy demands constant creative input which can exhaust players, character differentiation can blur with freeform aspects, requires system mastery from the GM to run smoothly
