If I were to capture the Hanging Gardens would I get the +1 population bonus, or is that a one-time ordeal?
If yes, then does the AI receive the same bonus for recapturing it, or at that point is it "Only one bonus for each Civ" whenever captured, and recapturing does nothing?
It's important because I'm currently facing a domination problem. I don't want to mess up my relations with the lovely Catherine who controls about 20% of the world's land and is quite friendly with me (apparently I am her hero, I'm everything she would like to be). So I'm looking at either taking out Isabella, who is annoyed because I've pushed Confuscianism around the continent and she is a devout HINDU (despite having the option to convert to Christianity, which she founded). However on the other hand Rome has both Pyramids and the Hanging Garden and they're much weaker. The only wonder that interests me is the Gardens because it would help me get over the population barrier since I already have a TON of cities (+1 to each would be great). If not I'd be better off taking out Isabella and getting her out of the way.
Also considering just gifting mass media when I get it to Rome and letting Caesar build the UN. I would easily win diplomatic victory at that point since Catherine and I control probably 60-70% of the population.
