Issues that stem from us is the fact we started with the original Axis and Allies and all the rule changes that followed in the coming version such as losing the ability to invade neutral nations, we used to keep that rule without researching new ones.
A big issues that seems to come up is a friend of mine who usually plays as Germany can’t seem to get it into his head that you can travel from east to west or west to east on the board and doesn’t understand this is allowed as we are playing a 2D game as if it was 3D.
