Hey, a few ideas I have: Make the organs separate civs, then each organ COULD, could have a few airbases, and you could have two bodies, one for things like heart, lungs, liver, kidneys, and limbs. The other 'body' is the digestive tract, and every organ has at least two airbases (relative to one another, 3d wise (you know, gall bladder is near the stomach, so on the liver/heart/kidneys side, you would have the civ, 'gall bladder', and they would control an airbase on the digestive tract side near the location relative to it's location on that side.)) This way you could include every organ! Also, I think that making the bacteria and parasites starting cities conected to the body (in such a way so as to only allow them in) is a good way to fix civ III's AI invasion, or should I say, ignorance of, the body. good ideas?
