I · The mandate

Every law leaves a legacy.

Rationing, citizenship, birth policy, artificial intelligence, faith, labor, historical truth and alien ecology become law. Decades later, those decisions return as allies, enemies, successors and crises.

30

Decades to govern

A complete voyage spans 300 years, with political memory carrying consequences between generations.

84

Political and character events

Each crisis offers four policies with immediate trade-offs and delayed consequences.

6

Competing values

Survival, order, liberty, equality, knowledge and hope cannot all be maximized at once.

10

Possible endings

Your institutions, population, leaders and constitutional choices determine the society that arrives.

II · The record

Read the history you created.

Policies enter a permanent ledger. Newspapers explain who benefited, who resisted and what changed. The archive preserves discovered events, laws and endings across voyages.

III · The voyage

Built for deliberate mobile play.

Adaptive politics. Factions remember previous decisions, radicalize and act against institutions that threaten them.

Generational leadership. Choose successors, manage relationships and amend the constitution as society changes.

Accessible interface. Large text, high contrast, reduced motion, continuous scrolling and safe-area-aware phone and tablet layouts.

Private by design. No account, tracking, analytics, advertising or network connection is required.
