When I disband a unit within a city, do I get anything in exchange, as I did in Civ III (e.g., some hammers or gold)?
Building the Three Gorges Dam doesn't make my existing coal plants disappear. But are they still producing green (unhealthy) faces? Are they still being included in the formula for city maintenance costs (assuming they were included in the formula to begin with)?
Is there any way to sell or otherwise destroy buildings, as in Civ III? If so, how?
If I conquer a city, or I receive a city in a culture flip, and I choose to raze the city, are there any diplomatic consequences?
Of all the different kinds of temples in my cities, only Buddhist temples give me extra hammers. Any idea why? My state religion is not Buddhism. I'm thinking it may have something to do with the fact that Buddhism is the state religion of the civilization that controls the Apostolic Palace, but I don't see anything in the description of the Apostolic Palace that speaks to that issue.
Forest Preserves seem to really suck. If I remember correctly, they only give +1 commerce (or +2 under Environmentalism), and they increase the infinitesimally small chance of a forest spreading, but it's still an infinitesimally small chance. Am I missing something? Unless my city has the National Park wonder, why would I ever want to waste a tile building a forest preserve?
Unlike Civ III, there are a number of terrain types that appear to be utterly worthless in Civ IV, e.g., peaks, deserts, ice, and, for the most part, tundra. Am I correct that there is nothing that can be done to improve the hammer, food, or commerce yields of these terrain types?
My corporation supposedly "consumes" a resource, but I still seem to get the benefit of that resource. (E.g., Mining Inc. "consumes" my iron resource, but I can still build iron-based units.) Is this how corporations are supposed to work, or am I missing something? I'm confused, because, to me, the word "consume" implies using something up completely.
