I've been thinking about this a lot recently: Should there be a mechanic that encourages you to give back a capital to its original owner? Or should the AI request its capital back in peace deals? Historically, I can't think of too many examples of a war ending where a civilization keeps a capital city as part of its empire (yes, yes, I know people are going to cite Constantinople, ect., I said *many*, not *none*). Captured capitals usually meant the end of the war: concessions were made and the capital is relinquished. But in Civ, that never or at least very rarely happens. Sure, right now there's a diplomatic penalty for taking someone's capital. But, really, who cares? Maybe a capital should be in resistence for more turns or some other mechanic should take place that would encourage you to give back a player's capital if not going for a Domination Victory. As is, I've never given back another Civ's capital (they often make wonderful production-focused cities), but it seems to me there should be some stronger reasons for doing so. Food for thought. What do folks think?
