Play Starport Compact

What you play

Read each faction's shortage, draft a contract, and spend three rounds.

A three-round negotiation prototype with energy, farming and shipping interests. Contracts must respect each faction’s visible red lines.

Controls

Read a faction’s ledger, select contract terms and advance the round using the visible negotiation controls.

Your first session

  1. Separate current stock from future obligations before drafting a proposal.
  2. Check whether each faction can meet its red line after the trade. Energy reserve, seed grain and berth capacity are different constraints.
  3. Review the remaining rounds before making a commitment that uses future production or shipping capacity.

Decisions worth watching

A promised future delivery is not current inventory. Do not spend it as if it had already arrived.

A proposal that helps one faction can still fail another faction’s safety line; check all three ledgers.
