If there is one... That allows you to raze capitals and/or city states? So many times their spots would be so much better by moving them by 1, or just so terrible that they aren't worth anything at all. --- PSN: Mercutio94596 SSF4: Juri User
I don't know of a mod that does that, but maybe you could gift the city to another civ then take it over again and raze it? Seems like a lot of trouble to do that, but it wouldn't be their capital. --- Common sense is the most uncommon thing in the world-some dude.
