Tribe

The tribe is a collection of the player's now-sapient creatures.

Direct Control
The player can give orders to groups of his creatures for several reasons, but mostly to ensure the survival of the tribe or contact other tribes.

Indirect Control
The player can also purchase different items for his creatures, such as weapons, musical instruments, medicines, and fire. The player can also upgrade the hut that his tribe is centered around (and maybe get more huts, unless his creatures all sleep outside), presumably unlocking better items to purchase. When the player upgrades his hut to the final level, he moves to the city phase and begins interacting with the world via buildings.
