Still think it's hardly something a medieval man (or dwarf or especially--goblin), grimy, unwashed and long adapted to the smell of his own sweat and feces, would do.
Dwarf Fortress is an incomplete game. Just because dwarves don't wash now doesn't mean that's the way Toady wants the game to be. In fact, if you have been keeping up with things, you would know that in version 41a Dwarves will no longer be as you just described, Elvis. They are actually going to use soap.
I now put this forward, since you clearly did not read it the first nor second time it came up on this thread:
some poor, common counterarguments
You need to work on # 2 and 3.
Denial of umbrellas just because you don't think they fit dwarves as they are now is a very poor reason not to have them.
I am denying umbrellas because they do not fit my idea of dwarves and medieval civilization,
period, not just the current game. The "unwashed" comment was not about the current game as much as it was about western medieval society in general. Everyone was dirty as hell.
I hate to bring a different world into this, but for the sake of visualization, could you imagine watching say LOTR, in the middle of which it starts raining and everyone pulls out their umbrellas?
I'll stand by this statement--to me, umbrellas as a practical item in this game are laughably nonsensical. That's my only argument here, that they're
stupid and unnecessary chaff in a game with enough clutter as it is. Can you give me a reason a sensible person needing to do all kinds of hauling, construction, battle etc would pick an umbrella over a cloak?
