851448 is an interesting map, where each nation has its own thing going for them. Red can quickly expand into several nearby towns, and has a weaker neighbor in Purple. But Purple can tip the scales and conquer Red's prosperous lands if Blue is also pressuring Red. Green is a stronghold surrounded by water and ports, with many towns it can safely hold. They also tend to be pressured by every nation at once, and become the almost exclusive target of the Red/Purple empire. Blue's homelands on the other hand can go almost undisturbed due to their turf being far removed from any of the action. However, they don't have a lot of towns they can easily control, and must be very aggressive into Greenland and the center of the map, where they can stomped if they don't carefully control their aggression. This map has a lot of back and forth, and I've seen every nation become an empire on this map.
Is there any reward for trying to be eco friendly and planting lots of trees and avoiding things that are described as being unhealthy, like the machines and farms?
