1. Is it just me or is the AI naval power filled w/ AI cheats? I'd say I lose a battleship to a destroyer about 50% of the time, if not more.
Bombard them first before attacking them.
AI ships will always return to port to heal once injured. So bombard them, hurt them a little bit on the first engagement. Then chase them down and bombard them some more. Don't attack until they're redlined or are about to make port.
2. As you approach the end game, all the AI opponents will turn against you, no matter how peaceful or generous you've been with them in the past.
My theory is, late in the game, after rails, factories and power plants, everybody gets a lot of production with nothing left to build but units, units, and more units. So every AI starts accumulating a lot of units.
Every turn, each AI makes a check: Do I have enough units to kill somebody? Most of the times, they don't, so they stay put. But with every AI accumulating units like this, eventually someone will decide to pick on somebody. And unforunately, that somebody is more likely to be the human player, because we think we're smarter than the AI's

, so we don't garrison 4 infantries in each and every city like the AI's do
The solution: ask them to pick on someone their own size

. Turn them against each other, then wash your hands clean after the 20 turn alliances are up.
3. Fascism is the best war-time government. So, now when I approach end-game, I switch to fascism.
I guess you haven't seen the power of the C3C Communism
Republic = a utility government that can handle everything that the game throws at you. Once factoring in the cost of anarchy, it becomes the best government in the game.
Communism = With courthouse and police station, every single city can become as productive as a core city. It takes a while to build up the previously corrupt cities and the newly conquered cities, but once they do... Good for The War that Ends All Wars.
Fascism = the government that replaces the old Communism in C3C, whos only purpose is for the AI to commit suicide in.
Democracy = a government that has advantages over Republic, but not enough to make a difference between winning and losing, but does have one nasty drawback that can lose otherwise winnable games.
5. When in anarchy, since you accrue money, but not research, should you put all emphasis into tax collection?
Neither tax nor research is accumulated during Anarchy. The gpt that you see during anarchy comes from taxmen, and the research that you see comes from scientists. Since C3C scientist produces 3 beakers to taxmen's 2 gold, I usually go with scientists.
