Axis and Allies G40 is a game unto itself.
War Room is a game unto itself.
I understand the compulsion to cross pollinate the games because the main core of players who have War Room are fans of Larry and his A&A line of games.
I think the games have different motivations and mechanics that make them stand on their own. Now that is just MO. You do what you want when it comes to house rules.
The one thing that I caution against is that War Room is a new experience for all of us. No need to knee jerk react to certain aspects of War Room and say Game X does it better so I will house rule Game X’s “view” into War Room.
I think World in Flames variable ending to turns, where you have no idea when a turn will end is superior to every WWII game that I have played. Yet, I feel that is a unique feature to WiF and feel there is no need to import that aspect into lets say G40 or War Room.
For people to understand one of the unique aspects of War Room, that you can only move 9 commands. Import that into AA G40 and see how much it changes the game. Because if you import the G40 idea that on your turn you can move every unit on the board if you so desire will totally destroy War Room as a game.
One negative of G40 and War Room is that Larry never put a finite end to these “games”. Thus that ensures the Allies will always win in less the Axis go hog wild early in the game. Thus the Axis never have to actually think ahead and play a defensive game. Games like WiF, SPI ETO, and Third Reich have a finite end to the war. If the Allies have not won and the Axis have not won by Sept of 1945 the “game” ends in a draw. Larry is obviously not a fan of a draw in his games, :}
Imagine if G40 or War Room had a finite end to the game. If the Allies have not won by the end of Turn #18 the game is a draw.
