And I will repeat my thoughts for discussion here.
When the Axis achieves the territory gains that they start with in '42 in '41 it is about round 3 or 4. The Axis have much more units on the board especially at the front in '42 than they do in the same time frame in a '41 scenario (round 3 or 4). Yes the Allies start with a few more units scattered around the world but I also think by round 3 or 4 in '41 game they ca nhave produced more.
