In Civ 3, my warrior takes about 100 years to get to the border of his country. A peace-treaty lasts a minimum of 20 years (if the treaty was made after 1950), and often must last at least a century. I understand why Civ 3 measures time in years, but often it becomes completely warped. I have no idea how this could be fixed in Civ 4, but somehow I think it should be.
