Governments and the economy: Civ needs some sort of economy. This would go along with the liberal/conservative slider i mentioned before. The more liberal you make your government, the less the economy can sway and the more conservative you make your civ, then the more the economy is able to sway. These apply to Republic and Democracy, as for Despotism, Fascism and Communism the economy cannot sway at all, Monarchy and Fuedalism can sway a little bit. How does an economy boom or stagnate? It is a combination of treasury (run a deficit and your economy goes to the dump), your GDP (finally a use for that thing that pops up when you press F11) and how openly you trade with other civs. A boom in the economy will increase the overall mood a little bit, but increase science and commerce. If the economy lags, then the people will get sadder, production will slow and corruption will increase. Every once in a while an equivalent to a "plague" will arise and could be called something like a "stock market crash" or something to that extent, and would be an instant lag in the economy. The range at which an economy can rise and fall is rather small until you get banking, and the range will increase even more once you get Economics and The Corporation. This gives much more stability and appeal to governments such as Communism because they can rely on a steady economy that won't fail them. However, the risk takers who choose a conservative Democracy can either be extremely rewarded or find themselves in an eternal depression. on to my second idea: I propose that there be various public services that one can invest in. These would range from public health to education, union support to civil safety (police, courts, firemen), all the way to business relief (not sure of the proper name for it, but it is basically something to help bankrupt companies). Under Communism, the cost to invest in the various areas is drastically reduced, to reflect the fact that the state has complete control of the economy, so thus has an easier time giving public services. Of course, communism could not get "business relief" because they have no businesses! Each slider has a certain effect on your civilization, for exampe public education would increase science and slightly boost commerce, union support would increase production, civil safety would slightly decrease corruption and make the people happier. This system of investing in the various services would also tie in to the idea of having some sort of Congress, Parliament, Meeting of Feudal Lords, etc. in that the various "factions" within the congress would want various amounts of money to be spent in various places. Although this may seem like it leans a bit towards Communism, it is mainly because in civ3 communism is very under-rated and SERIOUSLY needs a boost. Most would either choose Fascism, Democracy, or Republic instead of communism, plus I feel that this economy thing would allow for it to be risky to have a free market, which is true in the world (look at Africa and how quickly it depressed) and should be in civ.
