defending coastline

[wailoktam]

I wonder whether there is any good idea for sp(impossible + agressive ai) games in which you start near the coast. Besides playing as MA Shinuyama, I have to restart every time if there is a sea nation in the game and I start near the coast. When they attack you, you can only kick them back but you cannot go into the sea early in the game. And the war cannot end. As the Ai playing the sea nation would not lose any province, it can keep on throwing loads of chaffs on it. So while you are fighting off the harrass from it, others are expanding like mad on land. And after a while, they would come on you and you are finished...

I think there should be a way. If there is none, this is really a bad design issue.
