I think Persia might be the optimal play for the Allies under these rules – you can easily reinforce it from Stalingrad, and you can push either east to India or west to Egypt as needed. Persia’s usually not worth a factory in OOB play because it would only have 1 production slot, but with 2 production slots in Persia at the start of the game, you could really swing the center of the board toward the Allies.
Anybody want to test this out by e-mail? I’ll take the Allies with a factory and AAA in a modified Persia that’s worth 2 IPCs and has 2 production slots for as long as I can hold it. I wouldn’t ask for any further bid; that sounds like plenty to me.
