Hmm, log cabins already existed in C1 game, however these were not build able. They were static starting option. It would be fine include build able garrisoned log cabins as Ftoomsh suggested. I also got them on my whish list, however I called them blockhouses. Such garrisoned fortifications, even few types existed in ACFB game. They garrisoned more men, could be reinforced under fire and strangely stormed through open doors, that was not good. So, few improvements here are well come. Less men in garrison, weaker fire power, only some defence for up to 12 men agianst musket fire. Fire arrows, artillery or sappers with powder kegs are needed to destroy such building. Small sieges or blockade also could be practicable. If blockaded fortification will not reinforced, supplied or relieved by friendly forces after some time it could surrender, at last all garrisons needed some food, water and ammunition.
