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 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
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
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
