<i>300: Earth & Water</i> is a historical game for two players set during the wars that included the battles of Marathon, Thermopylae, and Salamis. One player controls the Greeks, gathered around the Athenians, and the other player controls the Persians, fighting for the hegemony of the eastern Mediterranean. Through five expeditions, each player aims to control more cities than their opponent.
The game engine is a card-driven system. Players raise armies and buy cards during production. Cards can be used to play an event or move an army or fleet. Events can provide advantages in battles or interfere with the enemy, but military action is paramount to win. Moreover, each game will change dramatically according the order the events occur. The rules are simple and the playing time is short, but both Greece and Persia have a wide range of strategies, so victory will challenge both players.
