Making a 3rd tier of wall for Carthage is too much. The game already have this kind of thing with "wooden" towers and "stone" towers being 2 different towers (when the stone should just be an upgrade for the wooden, not 2 different ones). Buildings should not duplicate their uses (in fact, I contemplate just getting rid of palisades as buildable structures in DE). Just my opinion. It would be much cooler to make a new model for the city walls, okay, that is the footprint of the Greek, Egyptian, etc. walls (standard size), and then make another set of new models (same footprint) for the uopgraded "Triple Walls" tech. This would be cool. Game needs more visual upgrading. The current Carthage walls are comically big and ugly right now anyway. I do like the "low" stone walls you make in that other thread (though they would not be useful for what I propose here).
