Ahmm, one could argue that wars tend to be bad for the economy. As for WWII specifically, there was a huge economic crisis in the states prior to the war and most european countries didn't fare well in that regard.
Now, during and after the war most participants had their economy practically ruined. Europe was devastated. So much so that people hungered for quite some time after the war was over.
Probably the notable country that actually gained from the war, economically, is the united states. Selling arms and food and having the war burn the grounds of other countries were factors that helped it I reckon.

I kinda like the game. Not perfect by any means but it passes the time pleasantly enough and doesn't require head numbing planning and accuracy like dominions does.
