This is a 2 player version of the campaign Noryang from The Conquers Campaigns.I have made some balancing changes:
Korea's wonder has been moved farther inland
Korea starts with a larger standing army,(this is because when a human player controls the Japanese raiders they could potentially defeat the Koreans without a fight.)
The hill castles where you find the admiral have been improved and a siege workshop placed there.
The Koreans cannot build castles or siege workshops, making it important to keep the hill base intact.
You start with both the Chinese troops and the admiral in the beginning
The Chinese are considerably weaker in numbers
Japan can be defeated by destroying all four of their castles
Japan starts with two town centers
This is a very simple map, but I hope it is enjoyable.
I might do a similar thing to the first El Cid, Barbarossa, or other campaigns in future.
