The Stone Age is now, and your children are the key to your future! In Tribes, the players are cave men and women. They hunt and gather food, make their tribal laws, and deal with natural disasters. But the object of the game is simple: Look after the children! In this game, the way to win is to have the most kids . . . and do whatever you have to do to make sure they survive. The players must know when to cooperate, and when to cut their losses and protect their own families.
