I've seen the AI raze lots of cities on monarch. Some times I take the territory they left vacant, they may have resources, or just an excelent spot for building. So I let them do the war, raze each other, and then go claim their hardly earned territory. That's one of the reasons I don't raze. I hate when another civ seems to be desperately looking for space, and has settlers in reserve, so when they find there's open ground, they just move there and take it. Some times I'm too busy at war to remember to transport settlers, or maybe I'm waiting for the dust to settle before returning to peaceful building. And then before I can take it, a new city appears. Especially if it is in MY continent

This inevitably leads to more war.
I rarely raze cities for placement. If there's a lot of unused space, i just build another city to take it.
And I never raze a city just for revenge. I don't like conquest victory, makes Civ3 seem like a RTS. I play for Domination, that fits my style better. So I try to conquer territory, you don't gain that by razing. Though I have no remorse reliving Sarajevo, taking up a mountain with a few infantries and 50+ artilleries, and auto-bombing those huge, populated, happy and productive cities down to the last citizen, every turn takes about 2 minutes to finish the bombarding, and I watch and actually enjoy, how every improvement is destroyed, civilians killed, soldiers injuried, till there's nothing left to destroy, the city is left a smoking ruin, their only citizen is unhappy, their defenders agonizing

then my cavalries just walk in and finish their hopeless defenders in one hit. Then I take the city, watch the aerial view, think of the "now" and the "before", think "was all this necesary?" To hell with regrets! It's war!!

Well, that was long!! I feel better now. Now, if you excuse me, my hands are itching, I have some civ3 to play and some cities to... uh... leave as they are!

Yeah, that...
I love this game!!
