Also, you mentioned that you have a game group with which you want to play A&A. If money is tight, one option would be to ask the members of your group to chip in…perhaps even to the point of splitting the cost evenly between all the members, and treating the game as the collective property of the group. Alternately, one person could buy and own the Europe 1940 game and one person could buy and own the Pacific 1940 game.
