The AI is too bad

[Lanthar]

I've been very impressed with the AI's use of pillaging. It's forced a change in my play. In Civ III, I got lazy and stopped keeping any kind of good defense in my interior. With CIV, even if the AI is losing a war, it still sends out multiple solo fast units that do nothing but pillage things in order to try and cripple my economy. It's forced me to adopt a hedgehog defense as a standard strategy, which tends to work well in multiplayer against humans, as well.

I get very annoyed everytime the AI slips by my borders and starts pillaging everything it can, but I appreciate the challenge at the same time.
