Just wanted to update this thread with something I noticed near the end of the live stream yesterday:
Near the end, Swen went into GM mode and placed down a dwarf. Then he opened up the Dwarf's info and there was a tab called 'appearance', which let you change his face, hair color, skin color, NPC clothing model pieces, etc. on the fly! Very nice addition to GM mode, might I say. There were some things we couldn't see down below, cause he didn't scroll down far enough to show them, but I wonder if "Race" might be one of them. I'd also imagine perhaps "Scale" could be in there. I guess we'll find out eventually!
