Does anybody use this method? What I have noticed on my Continent maps that civs usually start on or very near the coast. Consequentially, it is likely that their core cities would also be on or near the coast. So, when attacking civs overseas, I just land about 90% or so of my army right near those core cities and start throwing 'em on the defenders. Although the AI tends to defend their core cities better, in my games taking out the 5 core cities is much easier than taking out 15 normal ones. Without the heart of their empire, the enemy's economy will surely fall. Also, is there any penalty for having your capital conquered?
