| Best For | GMs 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. | GMs who want minimal prep and players who enjoy spending resources to shape the story. |
| Highlights | Highly 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) | Very easy GM prep, flexible character descriptors, XP for discovery |
| Considerations | Not 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 ecosystem | Players track most complexity, limited tactical combat, can feel same-y |
