Thanks for the flak, -er, responses.
I don't have too many others to discuss these things with, so the forum is the place for me. And I do appreciate the responses. WW2: The Struggle . . . is a game. And a simulation. I've been historical wargaming for a few years and I understand the things that have to be done to balance game play and history. And that is difficult if you want a playable game/simulation that will not take weeks and months to complete and not get bogged down in 1000+1 small print rules. I like Bob's suggestions re: the use of factories. I may incorporate them into the games my group plays. And thanks Mark too for the input. I fully understand.
And just for information purposes to give you more of an idea where I was coming from:
