If I were playing just Pacific I would play Alpha for sure. Now playing Global I just started using it and I am undecided so far.
Benefits for Axis
-America loses 3 planes it will probably have to spend points on and build and this can buy Europe time.
-Pacific Brittan loses 2 planes that in my games normally end up in Africa and makes things harder for Italy.
-Austrialia loses 2 planes that can be a problem for the axis at times.
Benefits for Allies
-I believe with Japan down 7 planes it makes more sense for US to spend some points in Pacific and venture past Hawaii.
-I believe the loss of seven planes slows Japan down and they have a harder time getting there economy going especially if US spends some points in Pacific.
Final Thoughts
My gaming group has played about 20 game so far with the allies winning around 80%, 10% draws and 10% axis wins in Global. Either we are just too dumb to play axis and can’t figure out how to save Europe or Pressure US enough or maybe the global favors the allies. I believe that to be true whether using Alpha or OBB.
