I'm a big fan of the Revolution mod. At the moment, however, I personally feel there are some things that could be improved. For example, several times now I've defected to lead a revolution and take over a revolting city. The only problem is the city doesn't stop revolting, and soon enough it'll go back into open rebellion and spawn another rebel civ. And when they take over the city, the revolt still doesn't stop, and eventually another rebel civ spawns. What I'd like to see is a sort of 'honeymoon period' after a recent revolution, during which there is no unhappiness or discontent. That would give the rebel civ a chance to get on its feet before attempting to fix the problems. My second suggestion is more radical. I'd like to see the discovery of new systems stirring up revolutions across the globe. What I mean by that is, depending upon game length, for 50 turns or so after a civic-granting technology is discovered, revolutions become much more likely, and during that time almost all the revolutionaries adopt the new civic. I'd also like to see a new civ introduced, the USSR, which will spawn some time after Communism is discovered as a major and powerful rebellion in the civ with the highest amount of unrest. Whoever researches Communism first gets the opportunity to take control of the new civ. The USSR gets the Red Army instead of Infantry, which are a couple of points or so stronger. It starts off with diplomatic penalties with any civilization running free market, hereditary rule or theocracy, and it can choose to control any revolution that occurs from then on, at the cost of a significant diplomatic penalty with the host civ. Its leaders should have strong preferences for relevant civics.
