Yeah, all the armies seem to be based on real world nations, but it's not always very consistent, though, since Green Earth also uses a Russian Hind helicopter that would fit better with Blue Moon and an American A-10 Warthog plane that would fit better with Orange Star for instance...
But I think some of the other units definately look like WW2 German units, like the Kugelblitz Flakpanzer anti-air, and of course the Stahlhelmets of the footsoldiers! ;o)
Haha yeah, the "cuteness" of the units is part of the reason why I like making them so much I guess... ;o)
I know about Flipit, yeah, Jim contacted me a while ago; people have always been playing with the idea to use my Advance Wars units for a tabletop game too, but it is very difficult to translate the rules of a videogame to a good tabletop game.
The rules of Jim's Flipit game are based more on other tabletop games than on that of a videogame so it should work much better! ;o)
