I'm playing for a Conquest victory in G+K. Before G+K, when Great Generals start popping up, I would use 2 or 3 for combat and rest for Golden Age. G+K altered the Great Person mechanics so much that I have to unlearn the above strategy.
The only non-combat function is building a Citadel and convert surrounding tiles into your territory. I have limited use for this feature and all I can do is to park each one into my cities.
Can anyone suggest a better way to dispose excess GG under G+K? Thanks.
