I must say that PTW is a lot more difficult than Civ3. I was playing on Regent for the last month or so and pretty much having my way with the oposition and was thinking about moving up to the next level. Not now, though.
I wonder if they did something to the AI? It just seems a lot more difficult now - and I haven't even made it to the Industrial age yet.
The other civs refuse to trade with me no matter what I do. It seems that I broke a treaty with the Ottomans a long, long time ago and everyone holds that against me. I wish I knew what the treaty was, but if it was when I broke a peace treaty, that was in BC and we are in the 1700's now. I can't imagine that they'd hold a grudge for this long.
Harbringer? Last night I was playing a game as the Romans against the Chinese, Germans, English, Egyptians, Japanese, Ottomans, Arabs, Carthaginians, Babylonians, and Persians. I was winning, but not by much. The Persians and I were well ahead of everyone else, although the AI's refusal to trade with me kept me two or three techs behind. It would have been worse had I not used a GL to build the Great Library. Anyway, for no apparent reason the Persians declared war on me. Then they made an alliance with the Arabs. Then the Ottomans (who are on my continent), then the Egyptians (I laughed because I had whittled them down to one exiled city far away). Then the Babylonians. Isn't it interesting that all of these civilizations either in the Middle East now or having been there long ago would gang up on me? None of the non-middle eastern cities joined the battle - either on their side or mine.
Anyway, I think I may have to downgrade myself to level two again. What is it, Chieftain, Monarch, then Regent? Whatever it is, I play the third one and will now go back to the second one until I learn any new tactics that the AI uses.
