Hi ltparrot73
In the customizations forum are heaps of community made files.
For instance see https://www.axisandallies.org/forums/index.php?topic=39696.0
So, what does it take?
Playing the Allies is a bit more complex because a suboptimal move for one Allied nation can end up being the most optimal move for all the Allied nations together. It’s something that is not necessarily related to attacking, but may be about production or positioning instead.
I feel the game is pretty even, usually the Axis player put a lot more thought in their play than the Allied player which probably explains the 6-12 IPC the allies are getting as a bid, on average.
Has more to do with the positioning the allies have as to why the allies bid ranges from 6-12.
