Hi guys, I was wondering on some effective strategy for expending Great Generals into citadels. In past I was a bit "citadel-happy," dropping them pretty willy-nilly - for example if I was getting pretty close to bordering a rival civ I'd tend to drop them one tile outside my border to steal tiles from their borders (obviously if I wasn't too worried about provoking them and had war in mind already). Another example would be if I was doing a conquest of a rival civ and had taken one of their cities with another close by - I'd drop the citadel to provide a little defensive waypoint towards the next city I'm attacking. I think one obvious use for a citadel would be if you're playing a tall empire, and focusing on defense as you go for a science victory - - if you have any chokes (tiles between two mountain ranges, tiles on isthmuses near coastal cities, etc) to your city, a citadel with a range unit would obviously make life difficult for any aggressors to get in. Anyway, to those of you playing above King - - what are some of your strategies and approaches to using this feature?
