Doomsday- Historical War

There should be a Doomsday but using the new historical world map, which could make the rounds more interesting because you wouldn't have so many countries clustered around. Or it could be doomsday with the countries All in, map. Which would'd make it difficult if you choose those smaller nations. Countries like the U.S and the Soviet Union can make them puppet states to fight with them, kind of like an alliance.
