WarrenPeace....I made my map way more simple than that. Everyone is assumed to know multiple ways to each territory. You are correct that the outlying areas and the various roads could be plot lines themselves. Other towns at the time include Bryce, and Brodrick and Jefferson (now west Sacramento), Carmichael, Freeport, Florin and Franklin, Montecello which is now under Lake Berryessa. Lodi, Herald, Knights landing, Yolo, Winters, Rio Linda and North Highlands.
None of which are appearing in this program (Campaign).
I stuck to building that were there in 1932 and still exist today. The purpose of capturing the building is that it will generate recourses which we equate to cash that then can be used to buy or upgrade troop quality buy equipment etc.
The real purpose is to have games with figure on a table but have players react realistically for campaign purposes. Most battles one player pulls out before the rules would required it. They see the end comeing and do not want to lose troops needlessly. If a unit escapes below half but with at least one figure, half the unit value is saved along with all upgrades, so the one figure is leaving with the light machine gun etc. on his shoulder.
