The Buildings needin my opinion only, of coursea lot more revision than the Units. There are a bunch of over-powered buildings, especially when they are compared to other civilizations that modify the same type of building. As such, I have addressed these in sections by the type of building being replaced. My stress here has just been coming up with ways to address duplicates and some of the more egregious examples of buildings being overpowered. Sorry for the length of this and, of course, reject/modify as you want. Colosseums The Athletics Complex is identical to the Odeon. I would change the Athletics Complex to +1 Culture, +1 Happiness, +10% Hammers, but remove the 2 Artists. In light of its Health benefit, I would drop the Sauna to +2 Culture. Courthouses The Seven Fires and the Maloca. I would drop the Maloca to +1 Happiness instead of +2. The Ziggurat. Shows as requiring PRIESTHOOD, not CODE OF LAWS. The Fanum is stronger than the Longhouse. I would take away the maintenance bonus for the Fanum, and change it from 1 Priest to 1 Free Priest. Factories The Fabryka and the Assembly Line. See comments earlier in thread. Forges The Igloo and the Potter. Make the Happiness bonuses resource specific: Fur, Whale, Ivory for the Igloo and Rice, Wheat, Corn for the Potter. Grocers The Woolsheds Civlopedia entry is incorrectthe text doesnt match the descriptive list, so Im not sure what it actually does. Monuments It just seems a little odd that the most powerful ancient culture items are Armenian and Olmec. I would increase the cost of the Stone Heads, and change the Khachkar to +1 Culture. In doing this, I would add a +1 Happiness to the Bora Ring. Stables The only real thing here is that it seems odd that the Batavian Stables outpower the Ger. I would recommend that the mounted supremacy of the Mongol Horde be preserved. Theatres The Opera House is listed with a cost of 120, which seems awfully steep. The Salegy Hall and the Pavillion. The Salegy Hall should not be as strong as the Pavilionmaybe dropping its additional culture to 10% or 15%. The Salegy Hall could also be reduced in cost to 45. Theatres None of the custom walls (Dun, Kings Tower, Diwars) are differentiatedall provide Guerilla I. Vary the promotions, and/or the price. Thats it! As a next project, I would move some of these around: there are 10 custom courthouses, 10 custom colosseums, and 10 custom theatres.
