Hi, I've been playing a new game in which I unififide Itali and I really wan't to make Rome my capital but I'm afraid the pope won't let me keep it. I usuly don't try to mess with pope when I play a catholic character and go as far as to let him keep the whole kingdom of romagna, so I don't really know what to do should I go for it and conquer Rome for myself or should I just leave it alone and make another city capital ?
