But it never fails in my games (Regent level) with 15 or 16 civs that around the late middle ages, the sharks start to swim.
Most, if not all, civs make through the middle of Middle Ages, but then seemingly without fail one civ declares war on another. Then within 5 or 6 turns, virtually the whole world is at war against that one weaker civ. Rinse, and repeat. Soon there are maybe 10 civs left for the modern age. The trick is making sure you're one of the civs that make into modern times.
If the AI thinks you're weak, they WILL declare war. And they will bring friends to the party.
This always happens to me, and right now Im embrioled in the middle of it. As the Persian's playing on Deity on Marla Singer's Huge World Map with correct starting locations, I had been planning to invade the Babylonians, my closest neighbor) as soon as I had built enough immortals to do it quickly. It was still like 700bc and, after engaging in techbrokering for the early part of the game, I had built up a lot of money. Well, I still didnt have iron working yet so I decided to steal it from the Indians (who had just sold writing to me and were pretty far away and a little weaker than me. Well, after stealing Iron working, relations with me and India soured and i knew war was on the horizon so I had been pumping out Immortals as fast as I could and moving them to my borders with both Babylon and India.
Well, as expected, India declared war on me, but to my suprise, within 1 turn, the Babylonians, Chinese, Russians, Greeks, Egyptians, Romans, and English (most suprising of all), had all joined India in their war against me. So, I thought I was totally screwed, but luckily, I got the Zulus to attack Egypt from the south and France to attack Rome and Greece, and the Japanese (even though they were weak as hell and didnt even have map making until I gave it to them) to attack China.
The Frech ended up getting conquered pretty quick and so did the Japanese, but I was able to totally thrash India and Babylon while the French were occupying the Greeks and Romans and the Egyptians had to deal with the Zulus. Then I negotiated peace with Greece, and they actually ended up attacking Rome. With help from the Zulus I conquered Egypt, and I was able to conquer all of China except for the islands that they took from the Japanese. So now Im still at war with Russia (who is stilla formidable power) and England, though Im not really worried about the English. I also am a little concerned about the greeks because even though Im at peace with them, they are getting too powerful because theyve all but conquered Rome. I guess all and all the war has really turned out good for me, but I cant help laughing about the fact that it all started from me stealing a tech from the Indians.
