Control the Plateaus or rule the Valleys. There is plenty of resources for everyone. Be careful when chosing your spot to rule from because each place has an advantage and a disadvantage.
Detail: 3 in the Valley. One in the middle with enough resources to rule the world. One in a valley tucked away in the cleft of a rock outcropping. One hidden behind a mountain cliff and waterfall and river with tons of rock and iron. 3 on the Plateaus. Two have nice access to a hidden section with lots of fertile ground,rock,iron, and animals for food. One atop a nice plateaus with only one access point to easily guard against any invasion.
Please tell me what you think and how I can improve on this idea.
