what if they did a mixed bag on town size? some towns are the mini cities we now have some are the small ones of yesturday and they can make a mid-sized town to complete the mix.
just like base size you can get the info on your map. thwn if you dont have a horde at your disposal you can go try to sink your teeth into something you feel your group can handle.
dont place them in any particular order, mix up the locations and distance so you dont have all of one size town located in any particular patern or distance from the front.
i am a Muppet, and even prior to becoming one of the happy dysfunctionals, i held no particular interest in taking the base or winning the war, but i do understand that it is a vital part of the motivation to play for some people so i do agree that their must be a compromise between the playing styles or the player base and thus the game may just dry up.
