Ha ha...I like Tropico, too....I wonder, though if Civ is a little too grand-scale for the edicts?
This is not the first time I've mentioned it, either, but the "social engineering" model from
Sid Meier's Alpha Centauri really was cool. It had four different tracks: Economy, Politics, Moral Values, and Future Society, and you could have different settings on each one. The settings you chose would have different effects -- positive AND negative -- on income, population growth, corruption (called "efficiency" in the game,) war weariness, and unit morale (akin to experience). The "default" option for each meant no benefits or penalties.
For example: choosing Free Market economics meant your society got a large benefit to tax revenue, but an even larger penalty for pollution. "Green" economics did the reverse. Planned economics gave you a reduction in income, an increase in corruption BUT a concomitant increase in city PRODUCTION.
In governments, Democratic government increase efficiency, but decreased the effectiveness of SPIES. Police State reduced war weariness, but increased corruption.
What made all this cool was that you could really customize your society. You could have a free-market economy, but have a police state, so you could fight wars successfully.
Here's a description about how these worked:

(if you check out the links, you'll see descriptions of everything).
The only "down" side to it was that there was no anarchy -- you just paid a certain amount of money (money was called "energy" in the game,) and the more changes you made, the more it cost. For example, just changing from free market to plannet would cost ~ $8, but if you wanted to change from democracy to police state, too, it would go up to ~ $24. I think this would be better represented in Civ IV by increasing the amount of time in anarchy, depending on how extensive the changes you wanted to make were. So just transitioning in economics would take, say, 1-2 turns of anarchy. That PLUS politics would go from 3-6, and changing everything at once would be, say, 10 turns.
Opinions?
