The layout of countries and their balance of forces looks good. Doesn't look very historically accurate though (ie Germany is too weak, France too strong, USSR too weak, Yugoslavia shouldn't exist, Spain stayed neutral and like Sweden and Switzerland shouldn't be able to be invaded, I think its odd that Italy doesn't control Piedmont, Sicily or Venice, but think there's too many SCs for it there.)
My personal thoughts on the matter is there should probably be two WW2 variants made, a European theatre pre invasion of Poland (at least give Germany the SC of Vienna as they'd already annexed it and throw USSR an extra SC, break up the Balkans into individual states, rejig Italy etc).
I think another excellent variant would be set around 1942 or 43 as a global map. This would reflect the maximum extent of Axis powers (I guess not too dissimilar to the starting positions in the game "Axis and Allies"), although being Dip there'd be opportunities for horse trading and switching of alliances.
That's my two cents.
