Fighters will be the same as in Axis & Allies 1914.
So the Atlantic shouldn't be crossed in 1 round? The US would join in round 12 if 1 round represents 6 months, and the winner should emerge around round 18. I'm afraid it would be harder to balance the longer the game is supposed to last.
Russia should be strong enough to last at least 12 rounds, but weak enough to collapse over the next few rounds. That doesn't look easy to balance to me.
What about making 1 round = 4 months?
In approximately how many rounds is 1941 GCD supposed to last?
