The problem with "real world" maps is they don't always provide a "fair" /"balanced" arena. Look at Mindanao...
That is absolutely true. On the other hand, life isn't fair. Why should virtual life make a difference? After all, the circulation of maps also changes the starting situation on each map, evening the odds. Why couldn't the current country on the southern side of the Mindanao just accept the situation as a challenge instead of waiting for the evident loss and map change? Waiting to be beaten is just so un-american! And yet the majority of players still come from the USA... Besides, on
any map the country situated on the bottom triangle has the psychological disadvantage of having to work their way
up.
There are locations on the Earth that could be transformed to tri-symmetrical (couldn't figure out a better word for that) like the surroundings of the Great Lakes. Indians, Inuits and Europeans. Or Englishmen, Frenchmen and Savages, if that sounds better. Another approach could be to take some identifiable spot and make a threefold kaleidoscopic image of it. How about a triple Italy surrounding a three-bay Mediterranean? Or a triple Iberian Peninsula with the Pyrenees in the middle, surrounded by seas?
