Anyway, tonight was my second session running DW. A bit more comfortable with the moves, and I managed to get the campaign headed in a clear direction, which means I can dig into developing some fronts for the rest of this arc.
As of now, though, I prefer Ultra-Violet Grasslands, which is the only other ttrpg I've run. DW's rule set is interesting, but I enjoy working in a distinct setting, and the setting here is almost totally tabla rasa.
Dungeon World is asking a lot by providing minimal setting and also emphasizing collaborative storytelling. Feels like they should have picked one or the other. There are probably RPG groups in which everyone feels comfortable constructing bits of the world out of whole cloth, but most players are likely more comfortable improvising within a suggestive framework.
