You are the ruler of a kingdom. Compete with your opponent's Kingdom by playing the subjects from your hand and acquiring Resources such as "Honor," "Gold," "Food," and "Land." Once you have enough Resources, construct a Royal Palace, a symbol of honor. Win by building two Royal Palaces more quickly than your opponent.
This game is head to head basically.
But if you have two decks, you can play 3 or 4 players.
