| Core Mechanic | Roll 3d6 under target number. Advantage/disadvantage system via character traits. | No dice, no GM. Players take turns adding Periods (eras), Events, and Scenes to a shared timeline. A rotating Lens player picks a thematic Focus each round. A Palette of Yes/No elements sets boundaries. Scenes are role-played to answer a specific question about the history. Play jumps freely across time. |

| Best For | Groups who want a single system for every genre with granular simulation and deep customization. | Groups who want to collaboratively create vast histories spanning centuries or millennia — perfect for worldbuilding sessions, one-shots, or as a campaign-creation tool for other RPGs. |
| Highlights | Highly customizable point-buy system, simulation-focused, one system for any genre | Flexible across any setting and genre, zero prep required, no GM needed, useful as a worldbuilding tool for other campaigns, simple rules anyone can learn in minutes, generates unexpected creative results |
| Considerations | Character creation requires significant point-budget planning, combat rules are granular with many modifiers to track, full system spans two 576-page core books plus supplements, GM prep is substantial for campaigns using multiple sourcebooks | Can produce incoherent timelines without group alignment, one player can dominate if others are less assertive, no mechanism to resolve creative disagreements, sessions can stall without a facilitator |
