I have had lots of fun with my latest Civ the Japanese on a Deity level Game on a large continent map with 8 civs.
I found that a Militaristic and Religious combo is quite powerful:
1) As usual, my neighbouring Ai had 3 cities as I was still building a temple in my capital. So I quickly build some archers and worriors and launched attack on the English
2) My troops went to Elite quickly and took over 2 cities. I kept the pressure by sending swordman into battle. Soon a leader emerged! I instantly build the pyrimid with him. This paves way for a potent Despotism military rush and high culture openning.
3) I rush built those cheap temples, cathedrals in all my cities, and started reaping in the culture points.
4) This game favors the attackers to defenders. In any era, the best available attacking units can always beat best available defenders:
e.g. Swordman attack 3, spearman defense 2;
longbow attack 4, pikeman defense 3;
tank attack 16, infantry defense 10
This margin only gets larger as the game progress. So for a similar cost always build the offensive units.
So if really pays to keep on attacking before you switch to Democrocy.
I wiped out English and Russians early with a combined force consisting longbows, swordman, pikeman and 2 samuri. I upgraded my troops as the tech became available.
Whenever they have new tech, i offered peace and exchanged for those tech. And declare war again cause i still wanted their land lol. I captured many workers and had them build a long road from the battle front back to home.
Dont know why the computer rarely build barracks/walls, that made my assault so successful. My Elite longbow/swords eat those regular spearman alive. And i was able to get 10 leaders by 600AD. I build an army with my second leader, rushed Heroic Epic with the 3rd leader, and from then, GLs flocked in!!!!
I did not complete wipe out russia, kept 1 of her city alive for "milking leaders". Leaders can only emerge after i use my previous one. So when i needed a new leader, i declare war on Russia, fought her with 15 of my elite troops, get a leader, offered peace. She is more than happy to accept peace cause she does not want to get eliminated, hey i did not want that either!
I got 4 leaders this way.
I rushed the following wonders all in my capital city by 680AD:
Pyrimid, Sistines Chapel, Bach's Cathedral, Newton's University, Theory of Evolution, Hoover Dam, Heroic Epics, Wall street(yes thats right, even the cheap ones.). My capital was generating 70 culture points per turn by 500AD.
My focus on culture really paid off. NON of my 45+ occupying cities revolted againsed me, cause their native country had less than half of the culture pts i had. Their citizens converted to my nationality in a snap.
I also leader rushed a forbidden city in a newly took over fertile river plain city with about 8 surrounding cities. Had about 30 captured workers join this group of cities, and massed developed the land around them. So in about 10 turns, this new city group was more powerful then my original around my capital!
Now it is in 680AD, 2 techs away from producing tanks, my capital has net produciton of 100/turn, and about 12 other can produce a tank 2-3 turns. I am all set for a all out conquest ending! Spaceship is just too easy now.
I did not research a single tech in this game, extorted most, store a couple, and traded some. Had gold on 100% throughout.
So for all you peace loving civers: Militaristic is the way to go. If you ever want to build a city like my capital on more difficult levels, there is no other option.
Interesting obervations:
1) AI can build a city on a hill, I saw it happen, and i took it over for fun.
2) AI never declare a war on you for no reason even though it had a far more superior military. As I wiped out 2 Ai, had the largest land area but a small military, the other powerful AIs just sit there and had their troops on "Patrol", never even tried to capture my undefended cities once. How nice, So I never provocated anybody , just busy trading with rest of them.
3) Seems the AI's can get worker/settler from the Barbarians, I captured about 10 of them, once I joined them to my cities, they became my citizens instantly Cool, no assimilation needed.
4) Since so many of you complain about the city overthrown problems, here is the solution, work on your culture early, and attack those AI's having fewer culture points than you. Also, if you wage war early, never on more than 1 opponants, cause your economy is so fragile, the AI will always outproduce you. But you can rely on good tactics and judgement (unit combo, picking targets, using terrens).
5) denying resource of you enermy, I offered gold/res to every other AI to have trade embargo against China, it did not get rubber throughout. So he can only use rifleman against my tanks in a few turns hehe.
6) I got 1/3 of Russian cities for "free". After I took over 3 large cities, I offed them back(along with 200 gold/turn) to Russia for 5 other smaller cities, she gladly took it, only to have me declare war on her again and took those 3 undefended cities back. I end up with 8 cities in 1 turn, 5 of them with my own citizens and 3 resisted for just 2 turns. Of cause she never got her 200g/turn
I can post my saved game if anyone is interested at 4000BC and 680AD
