I have a Map Idea, its a little different so just be open minded. The map would be Michaelangelo's David. I've learned a lot of Geography and History playing here and I think something can be learned playing this "map".
This is one possible picture of it and also a possible division of territories:

Bonus would be: Left Arm, Right Arm, Left Leg, Right Leg, Torso.. and maybe the Head and the Ding Dong could be other. Yes, the penis would be called Ding Dong xD.
Please feel free to suggest anything on the fixing of the picture, the division, the bonuses, gameplay etc.
