Well, played it a few times now and i can tell you; this game is anything but historicle ! It doesn't even come close
There's just too much compression of time and forces that it hardly can be called "historicle".
few examples:
1) When i play German from 1939-polen, i never see one britisch unit (BEF) when i am invading france.
2) subs travel 250 miles (5hexes) in one turn, Airplanes 300miles and battleships/cruisers/dlightcarriers travel the world like they were JET/nuclear propelled
3) in a fifty mile radius you can operate with only one unit. Funny when i see that Germany launched "Autum Mist" in 1944 with 2 panzer-armees and a infantry-armee in a very small area.
well, you get my point. So if you're after more play-balance, ala. But don't even bother to make Sc more "historicle". In it's current form it will never be......
In a real historicle game there should be many more factors included, where can i get the manpower, resources and money to support your massive armee. Do i put my steel in tanks or battleships ? How can i suffient re-equip and supply my heavily losing material units. Shall i wait another 3 months to equip my PZiii with /L60 or like hitler send them anyway and recall them back later. And the list could go on and on.
So any WWII wargame isn't a historicle correct game, it only tries (if that's their intention) to come close to it as much as possible and yet it have to stay "playable"
