The AI is just one of many things I like about it. In short, whatever Civ does, Old World probably does it better, all without giving mega-bonuses to the AI.

It has a lot more going on than Civ (1 turn in OW is equivalent to about 3 turns of Civ), but somehow it's a lot more polished. There's a free demo, feel free to try it. It's often on deep discount as well. It has a 200 page manual. I find that skimming a manual gives me a good feel for a game before I play it.

The lead designer is Soren Johnson, who was also the lead designer for Civ 4, so if you liked that particular iteration you might like OW.
