ghr2,
I would agree on your number of 60-70%. Unfortunately that is what the US should at the minimum be spending against Europe to maximize the Allies chances to win. The 6 victory condition for the Pacific forces that 60-70% to be ineffectively spent in the Pacific. That is why I don’t like it.
So far I can’t tell how unbalanced the game is. I read most people complain the axis now have the advantage. But in the games I have played, playing with the 6 victory city rules most definitely puts the Allies at a greater disadvantage. So much so, no of my buddies like to play with it.
We are near agreement on some house rules that keeps it realistic in terms of the history and did some research on how many resources were spent on Japan vs. Germany and on Navies vs. Air Forces and Ground units.
So far it seems that it needs to be easier for the US to get to Australia to better assist, we are introducing a “Merrills Mauraders” rule, and we are dramatically making Naval units cheaper.
This is to encourage realistic Naval action in the Pacific without the silly 6 victory city rule.
Bottom line, Japan can capture 6 cities and win the game while obviously losing the world war.
