Hey, I'm new here and I sought out this forum because I've got some ideas that are (I think) good for a CCG. I'm wanting to do something similar where I have forces laid out on the table before the real fighting starts.
There is an old Civil War game called Dixie where the players do this type of thing. The entire rules are available online so go check it out.
