The game features its hero, caveman B.C. Bill, setting out to build a family. He is armed with a club, with which he can clobber a variety of roaming creatures. These creatures include: cavewomen, who can be dragged back to the cave as "wives"; food with legs, which can be roasted on the fire and dragged back to the cave to feed the growing family; and dinosaurs, predators who will eat potential wives and food, and kill Bill on contact. Bill can also die from: burning on the fire if he has no food; a broken heart, if too many wives leave the cave; and starving to death if he can't feed his family. Source: Wikipedia, "B.C.
