This is the first time I've gone Autocracy, and I have to say, it's pretty bad. The only nice thing about it is there are a good number of useful happiness bonuses. But the Level 3 bonuses are terribad. Cult of Personality doesn't fit at all with what Autocratic civs want to do. Gunboat diplomacy is laughably bad - I have pretty much the best military in the world and that's not enough to scare pretty much a single city-state. And Clausewitz is ok I guess, but a one time 50 turn bonus isn't really what I'm looking for there.
