I seem to be in the same boat as the OP. Yeah, yeah, I’ll get Civ4 sometime, but meanwhile I want to get the maximum enjoyment out of Civ3.
Fact: the AI cheats. They know where all the resources are at the beginning of the game, so they’ll plant down cities in random places knowing oil will be discovered there 2000 years later. They also know your exact military strength at all times.
You can actually use these to your advantage. Retain a large military, even if some of the units seem extraneous. Diplomatic negotiations move smoother when the computer senses you have a stack of 15 swordsmen, even if they’re on the other side of the continent.
Also, aside from an initial burst of planting cities, I like to conquer cities. The computer knows exactly where to place them - who am I to argue?
Fact: the AI cheats. They all collude to research separate techs, and then sell it to one another for a discount.
At the beginning of the game, I almost always set my research to 10% and gold to 90%. You can’t keep up with the AI in tech, so why bother? Just buy it (or beat it) out from them later. The prices go down as more people have it; you’ll always be a step behind, but you’re only really in trouble when you’re 3-4 steps behind.
At some point, usually during the Middle Ages for me, I turn the corner. This usually involves a big score - beating down a rival to the point where they’ll give you all their tech for peace, for example. Better yet, find an AI that’s about to get knocked off by another AI. Try to get an alliance against the dying AI for tech, and then sue for peace and try to score more tech (you’ll take a reputation hit for that one).
Basically, at that point, you start researching yourself, and your goal is to get a tech that nobody else has. Set all your cities to produce beakers and emphasize production. Good ones that the AI often skips are Military Tradition and Medicine. I also scored with Invention once too.
Start with the richest AI and work your way to the poorest AI. Squeeze as much as you can out of everyone, and most importantly, make sure that you give it to everyone - because otherwise the AI will trade with each other.
If you’re successful, the rest of the game is pretty much cakewalk. You can pump out a tech every 4 turns, and when you sell it to the AI, they pay for 20 turns. Sooner or later, you essentially bankrupt them - they cut their own research to pay for yours. You’ll rule the rest of the game with a 5-6 tech lead.
Little tips and tricks:
-
Read about “Ring City Placement” on Civfanatics. I don’t know how much it helps, but it’s pretty cool. I usually build a 5.5-square ring and an 11-square ring, and then build a Forbidden Palace far enough away and cram a lot of cities close to it.
-
I throw the AI 1 gold every few turns as a gift and it seems to help their attitude towards me.
-
If you fall more than 5-6 techs behind, you’re toast. Sooner or later your pikemen will end up getting rushed by tanks.
I just give up at that point.
