Something that I fooled around with for a bit, is giving the US the 30 IPC Pacific bonus for going to war. They get it straight away and it only works for one time. Along with a 5 IPC Bonus for being at war with the Axis. (Happens per turn)
Another thing I do at times is that I add a US infantry to Midway, Guam, and Wake Islands. I also add French Infantry and French Artillery to Indochina. Creates a minor road block for the Japanese, so they cant just walk in and take it.
@Narvik:
It is designed as a balanced game, if the Axis win all the time, you need to learn to play the Allies correct, not change the set up or income
I would like to point out that it is virtually impossible to have the Allies win in a timely manner using OOB. The only realistic way for the allies to win is to have the Axis Surrender. For that to happen, 1 of 2 things would have to happen.
1. The Axis Player Blundered way too much
2. The Allies played, really, really well
To respond to the first post, I think the Axis have enough money, I just think the Allies need a bit more. You dont want to hand them the game, but throw them a bone, to help them out.
