I don’t know that an Allied victory is inevitable. That is to say, I’ve won with both sides against intelligent competition. Granted, I’ve played just 3-4 games of Spring 1942. However I have played many Revised games so I’m quite familiar with the map and the game.
Has Japan been contesting Africa in your games? I usually take Australia, sometimes New Zealand and Hawaii, and then take Madagascar and trade African territories with my battleships to bleed off Allied units so the Allies either send a constant stream of units through Africa or they concede Africa.
Are Japan’s fighters used as a tool to help Germany advance? Example, when they aren’t needed elsewhere, I like to land my fighters on French Indochina, India, China, etc. so they can support a German stack advance to Ukraine or Karelia so that the Soviets can’t make a favorable attack.
How long does it take for Germany to be broken? By that, I mean not captured but limited to stacking Germany and trading its borders.
If you’d like, I’ll take the Axis in an ABattlemap or TripleA forum game.
