You are Littlefoot, the Longneck. For countless generations, dinosaurs had always stuck to their own kinds. Ever since you were but a child, you have successfully united the herds of the Great Valley. Now, the world is changing, but you see opportunities. You are convinced that the herds under your leadership should no longer be held at the mercy of nature, and can now forge their own destinies. Oh, Great Leader, Littlefoot, are you ready to lead your followers to greatness? Can you build a civilization that will stand the test of time?
