I guess starting this date presented a lot of variables which I've had in mind for a while. France is no longer a major player.
England stands alone (-except for help from the US, which I think historically the Congress approved Lend Lease this month, July, 1940).
Is the Luftwaffe, Kriegsmarine, and Wermacht up to the task of Operation Sea Lion?
Italy is involved as they declared war on the Allies when they saw France was down to 8/9 of a 10 count. But where will they go? Eastern Europe is non-aligned and alliances are up for grabs for awhile. What will the Brits do with France/Vichy and that navy? Will DeGaulle prevail into having the French fight on despite the loss of their homeland?
In the Pacific, China and Japan are slugging it out and just what will the Japanese do? Did Khalkin Gol (the 1939 Japanese-Soviet skirmish in Mongolia) really show them the difficulty of going north and west instead of south?
It's just another optional scenario. Granted the amount of time is not that great, that is, if you are a "serious gamer/grognard," which I am. Been playing wargames since my first AH purchases in 1964-5 (Midway and Stalingrad). The enjoyment is in the playing (and possibly winning a time or two)! And now, with WW2: The Struggle . . . I hope to find the opportunity to try somethings I've been wondering about. A&A and World at War game systems were okay and good. But now, with WW2: The Struggle . . . I really have a chance to "git 'er done."
