Overview

Eminent Domain is a deck-building empire-building game where each player’s abilities are driven by their deck of Role cards. Every turn, you choose a Role (Survey, Colonize, Warfare, Produce, Trade, or Research), adding that Role card to your deck and executing its effect. Opponents may Follow or Dissent. Survey planets, Colonize or Attack them to flip them face up for Influence, Produce resources to Trade for Influence, and Research Technologies. The player with the most Influence at game end wins.

Components

Setup

  1. Each player gets a 10-card starting deck: 1 Politics, 1 Warfare, 2 Colonize, 2 Research, 2 Survey, 2 Produce/Trade.
  2. Each player receives a random Start Planet (face down).
  3. Separate Role cards into 5 face-up stacks on the central display.
  4. Separate Technology cards by type (Fertile/Advanced/Metallic) face up.
  5. Place 24 Influence tokens in supply; set 8 aside as reserve.
  6. Shuffle Planet cards into a face-down deck.
  7. Each player draws 5 cards. Hand limit is 5 (modifiable by planets).

Turn Structure

Each turn has 3 phases:

1. Action Phase (Optional)

Play 1 card from your hand and resolve its Action effect. Actions cannot be Boosted or Followed. Discard the card after resolving.

2. Role Phase (Mandatory)

  1. Choose a Role from the central display.
  2. Take 1 card from that stack (if available) and place it in your play area.
  3. Boost: Play additional cards from your hand with matching symbols. Symbols on face-up planets also count.
  4. Resolve the Role effect (including Leader bonus) based on total symbols.
  5. Opponents react (clockwise): Each may either:
    • Follow: Play matching symbol cards from hand (plus Empire symbols) and execute the Role effect (no Leader bonus).
    • Dissent: Draw 1 card from their deck.

3. Cleanup Phase (Mandatory)
