I think that when you capture a city, all of its improvements should be sold and you should get the value (at least half the value) of them, or some science points. I mean, if you loot a temple, there is some treasure you can get, or a library science bonus or something. I get sick of invading a city, getting no gold, and having to rebuild everything. One time I had a bank in the city, but the rest of the time all buildings are destroyed.
Anyone agree?
