I'm currently playing an Immortal game, normal size map, lakes, as Montezuma. I've got Alexander to the Southwest and Caesar to the Southeast. Both DoWed on me by 400 AD. My army is such that I can absolutely crush one of them while holding the other off at my border with a few token troops. The problem is that going after either country proper is about 9 turns hiking for my Longsword/Rifle and Treb/Cannon army. Going to take rome would leave my soldiers 18 turns from the Greek capital. Being a lakes map with roads being the only way to connect, captured cities won't really be easy to link up to trade routes. I also have Egypt and Spain who are much closer so the cities seem to be a way better fit for my next wave of puppet expansion. What is the conventional wisdom regarding early/midgame long distance wars? Defend only, kill enough units to get extremely favorable peace terms, or go conquer?
