In response to the question "When gaming a city fight, do you all try to match the scale/size of the scenery to your miniature troops:"
A true scale creates overpowering buildings and the combatants are very greatly diminished. So a smaller scale for buildings with regard to their volume, but not their floor plan, removes this diminishment. I have not tried this, but you could use the Disney World trick of reducing the height of each floor above the ground floor. See Forced Perspective.
