From the review:
Cavemen: The Quest for Fire is a card-drafting game in which players take the role of tribal leaders. The tribes compete for opportunities to hunt dinosaurs, recruit tribesmen, and discover new technologies, vying to be the first with enough knowledge and prestige to invent fire and usher in the age of modern humanity!
You have two resources to manage: Food and Teeth. You must spend Food each turn in order to keep your Tribe from starving. Teeth indicate prestige among the tribes. Use Teeth to bid for the conch and to acquire Cavemen and Caves.
