Also you miss my point on the subject at hand.I am talking about MULTIPLAYER. The place where your opponent attacks both by land and sea and spread and optimises his forces for the sole purpose of capturing your citys.And there you can see how UGLY BROKEN the city defence is because you can`t have a small army defending every city while he can choose his battles and one-turn snipe.
Your opponent won by having a competent strategy? Horrors!

Sorry but I had to giggle when I read this, because this, to me, demonstrates that the underlying game mechanics for combat are (reasonably) sound. If the combat AI were even remotely competent I think these boards would be filled with people whining about how hard the game is, rather than how easy. Theoretically this should be pretty easy to fix with patches, or mods if the devs fail us.
I do believe many of the current issues people have about the game mechanics being broken (read: exploitable) would be alleviated greatly if the AI put up a truly scary military threat throughout the game.
