All player lands are surrounded by and connected by a river of water. The rest of the map is jungle with plenty of pathsways. A navy is a must! Use the appropriate map size for the number of players or strange things may happen. From what I have seen the computer dosen't even get to Feudal age. If anyone wants to make, or knows of an ai that will work for this map, please feel free to let everyone else know.
If you want the computer to be a stronger player you need to add this line to the begining of your RMS.
#define ISLAND_MAP
This tell the computer AI to load its "warboats" and "island warboats" subscripts. Without it the computer is going to be weak. I don't think a whole new AI is needed.
