I'll take a spot on the list.
As far as mist and clouds go, isn't it possible to get rid of them in advanced world gen.
I'm not sure we need the distractions, but how about mod in an extra civ like the High Elves, Orcs, or something.
Just something for a little extra flavor.
Um... hey how about we pick some colors to act as the fort's colors and ensure that there are dyes for the colors.
It will make the clothing industry interesting and we will be able to see the Stonesense dwarves running around in the official fort colors.
