The first two players to join the game are the kings; their goal is to kill the other. The other six players are the vassals; two vassals share control of the sea and abundant wood reserves. Two vassals control the middle plains, where farmland is available in large amounts. The final two vassals share the mountainous regions to the east, where gold and stone abound. The goal of every vassal is to acquire 5 relics. The kings start out with the relics, and can trade them for favors from the vassals. However, while alliances are often necessary for resources, banditry and betrayal are better methods for gaining relics than faithful service. Only one player can win, so it is important to hinder the others while putting your own plans into motion. It's been thoroughly playtested, but any feedback would be appreciated.
My friends and I play this multiplayer ever since I made it, and it might be the funnest LAN game ever. One time one of the kings was surrounded by the other king's castles because he was not playing very competitively. He was about to die, when he decided to hold himself hostage and threatened to send his king to his death. The vassals panicked and each sent a flood of petards to the rescue, destroying about six castles and lifting the siege in the blink of an eye. Such is the power of politics.
