I’d love to see a combined Battle of Britain/Battle of the Atlantic A&A game.
Britain getting squeezed, needs to decide to invest in destroyers, planes, or transports/land units for an attempted invasion.
Germans need to decide to invest in subs, planes, or transports/land units for an attempted invasion.
America limited in its ability to support. Maybe a 3rd player.
Russian Front (or perhaps the tip of Africa) a wild card; as, if the Allies can successfully shift troops to either, the effect on Germany would be akin to an outsized Industrial Raid, simulating German forces pulled to other fronts.
First country to land troops on the other’s beach and hold for one round wins? Or maybe just if Britain holds out for x amount of turns? Maybe both?
