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.Anyone curious about the absolute boundary of what an RPG can be: a single-word game about embodiment, physicality, and being a worm.
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)Entire game is a single word, playable as tabletop or LARP, zero barrier to entry
ConsiderationsNot playable out of the box: requires significant GM assembly, steep learning curve to understand which mods fit your game, every roll involves choosing which dice to keep plus an Effect Die which slows resolutionNo mechanical structure: no dice, no stats, no resolution system, one word of rules text with no GM guidance or scenario framework, single session only, no character creation or advancement
