I'm a bit of a wonder perfectionist in Civilization, and I like to have a monopoly on them. However, sometimes another civilization sneaks one by me; in those situations, I like to conquer the city that has it to complete my collection.
In previous versions of Civilization, you had the ability, through demographics, to figure out what cities had wonders. But I can't seem to find anything like that in Civilization 5: the closest things I've found are the periodic "top 10"-style lists that'll mention how many wonders a civilization has.
Is there better way to figure out exactly which foreign cities have wonders?
