The ancient Galactic Realm, ruled from the Core Worlds of the galaxy, is waning. Now, the barbaric kingdoms that lie beyond the galactic frontier are amassing their strength, choosing this pivotal moment to strike at the heart of the fading republic, establishing new empires built upon the ashes of decaying civilizations. But these outer systems are not yet strong enough to engage the forces of the Core Worlds directly. The young kingdoms must first gnaw at the edges of the crumbling frontier, developing new types of units and shrewder tactics. They must build up their energy resources to launch magnificent fleets and overwhelming ground forces. Then, when the time is right, they must strike at the galactic core itself, claiming the most exalted planets for themselves. Core Worlds is a deck-building card game for 2-5 players. Each player controls a barbarian Star Empire represented by many cards. Throughout the game, players will invade Worlds and draft new Units and Tactics into their Empires. Each card lists its Empire Points in the upper right corner. The player whose Empire contains the most Empire Points at the end of the game is the winner.
