You'll win the war if you supply the villages with goods and gain the Elders' favor.
In the two-player game Four Tribes, each player takes on the role of a powerful monarch in conflict with the other during a time of famine. The war is at a stalemate, and both leaders decide that the key to destroying the other is to recruit the help of the Northern Tribes! Each player attempts to sway the Village Elders of the Four Tribes to join their cause by supplying each village with desperately needed supplies. Win the village, and you gain the favor of the Village Elder! Gain the favor of enough Village Elders, and you will win the support of the Four Tribes and be victorious!
While Four Tribes is a two-player game, a four-player variant will be part of the finished product.
