Good concise guide. Excellent points about including some cats. Love your ranged nuke, that's almost exactly how I build my ranged nukes.
What are your thoughts on Breakthrough attack, i.e., when is the best time/situation to use breakthrough? When one can clear out a city's harbor with LS nukes first, it is not necessary, obviously. But, once a world gets past the early game, bireme walls can get seriously massive, especially when the enemy knows you're coming after a particular city.
I'd be interested in people's thoughts on this, as I am a little fuzzy regarding the math/efficiency of using breakthrough.
EDIT: just realized OP was from last july, so might not get the OP's input. still, interested on what others have to say.
