A3 still has some kinks in my opinion, but its damn close to as good as we are going to get for a board game of this size.
The convoy system, economic warfare, and tech are all lacking.
But combat, setup, National Objectives, are pretty solid.
As for an advantage…I think the axis has a good shot at winning with haymakers.
They can get to Moscow pretty quickly and that pretty much ends the game…or Japan can get dangerously close to a VC win very quickly in the pacific. (within 1 VC almost the whole game)
Even Italy can become a monster, the 3rd axis power really helps the game, gives the allies something to worry about.
In the long haul though, Allies dominate.
We haven’t had too many close games…most are runaways.
Either the Axis steamrolls to Moscow or Calcutta, or they flounder out of the gate and the UK is in Greece and the Balkans in a big way by turn 3, and the US has a massive force at Gibraltar ready to land troops anywhere in Europe.
