I do not understand why some pcity modules should be limited to only the
ground floor. I would like to be able to build things like a weaponsmithy
down (or even up) a level from the ground floor to get some better use of
space, or fill in space on an upper level with a wall to build above it.
Currently, the limitations make city-planning less fun than it could be.

Now if it is a code thing, that would make sense, though at this point I
wonder if it could be looked at. If it is a balance thing, perhaps a bit of
explanation would be nice, so that I can sleep at night knowing there is
purpose behind all...
