I hear alot of people say that revised is more complicated than spring 1942. Now I played the classic version when I was 12. Sure it was a long time but aside from the tech and the board being diffrent I dont see to many changes from the two, and neither one really seems more complicated than the other.
So what happand in revised that was taken away that makes it more complicated than Spring 1942
Other than the Technology and the National Advantages (although the NAs were optional) the game system is essentially the same. I almost never play with Tech because it can be a game breaker.
