I have recently noted something vs an opponent that forfeited a match vs me. I was playing the South, and I was launching an attack into Maryland in 1861. The success there was alright but he managed to stop me right outside of D.C.! Then the game halted to a permanent standstill.
In the East, you have usually have both sides staring at each other with the Corp System, 3 to 4 Corp each strewn across a 250-400 mile front... They support each other usually in 3s depending on the real estate held, best to give or take to get that optimum amount. With 2 to 3 divisions per. This makes it pretty hard to gain ground. Without luck and given the terrain, rivers and fortifications between Alexandria and Manassas if you built there. I don't know there is an easy way or if any way around this? One side would really have to invest in Uber numbers to win. This is repeated in every game and every side again and again and out west as the numbers of both armies swell through '62.
The large 100k stacks of History that fought through one essential piece of real estate seems less present. I don't know how vividly this represents history. Though any player know's what I'm talking about that's played 10 games. Most game as the CSA go this way, kill the Union in D.C. by '62 or by late '62 be killed by a 2 or 3 to 1 Union advantage in the East and or a slow death everywhere else attempting to hold down your essential real estate.
In history as far as I knew the Corps marched in unison, more or less as one body. They weren't strewn 350 miles? That or I may be entirely off. I just remember in the offensives Armies planned and executed with Corps more or less together...
I know this is abstracted and made as such by gameplay and perhaps nothing better exists just stating something. Which seems to leave most CW2 games to about 30 turns Max. Unless I am mistaken?
