I was playing a game in regent. Did quite well, I knocked out the Iriquois second city and every time they built a new one, I knocked that one out, made peace and took all their money. Eventually I had about 2 pikemen per city defending when the german's attacked and took two of my cities with about 15 horsemen. Then the Romans jumped in, followed by the egyptians and greeks. They ALL allied against me and relentlessly attacked with inferior units and overwhelming odds and lost unit after unit while slowly wearing down my pikemen. I took a couple of their cities trying to get peace, but they wouldn't make peace. Finally they made peace when I took 4 german cities with some knights, then they declared war on me a few turns later. I gave up since there was no way I could keep up being beaten on 5 to 1. I can't stand this game when you are teamed up on by the AI. Its really unfair, its the one thing about the AI I can't take. Now I've learned my lesson, I'm going to start trading with the AI as soon as I can, even though they never give you good deals, to establish good relations with them and I'm going to build equal offensive and defensive units. It sucks when you have 3 pikemen in a city and one in another deep in your territory and you can't prevent the AI from waltzing up to your weak city and taking it out.
