So I've worked out my Tradition strat pretty well thanks to posts in these forums but really struggle with liberty. If I'm going liberty, I'm playing a Civ that uses ICS/REX or both, and can manage that (for the most part) but never end up getting the NC because I'm building cities too quick. So the question is when should you build the NC? Should you stick to just capital and go straight for NC then expand? Build it after a certain city #? Vary every game? Any tips/advise for liberty openings would be much appreciated. Thanks!
