Man if you balance guys amde a WWII game your Tiger tanks wouldn't be any better than your Shermans, as for you hard core historical accuracy guys, It would take as long to play the game as the acctual events took.
I don't think so. If a balance guy made a WW2 game, the Tiger would indeed be better, but it would cost significantly more meaning the other player could buy several Shermans for the same price. The skill would come in making sure you use your numbers to beat the superior Tigers, and as the Axis the challenge is to fight the Shermans were they cannot use numbers effectively. (Unable to flank, fighting at long range etc.) See, historical accuracy and balance are achievable!
