I adopted the 4 castles map and feel that I improved it.http://warlight.net/Map?ID=5052
Mainly I wanted to fix broken connections and bonuses... But with Fizzer's prodding I also brought the map up to current standards, to have connecting lines, numbers fitting inside, territories labeled, etc.
Finally, I added in alternative starting distributions that I think add a lot of dimensions to the otherwise monolithic map.
I don't think I changed any aspect of the map in a negative way, and feel that I only made improvements, thus taking one map and making it a bit better for all of us, rather than flooding Warlight with another map with more problems.
Sometimes the original creator just doesn't have the time to clean up minor aspects of the maps. I did.
