Oh, but some (minor) expansion actually happens in this post.
Despite my post over there, I'm actualy mulling over throwing in my hat for GMing. I think DitV's resolution system would work interestingly for PbP, and I'm brimming with ideas (and time). My hangups are that I don't quite grok ceremony and sorcery, and would like to play the system in the flesh another time or two before trying to run it online.
Edit: After re-reading the rules, I realize that I already pretty much got sorcery. I was looking at ceremony as being a superpower, and it's not really, it's more of an extra option (similar to Mountain Witch abilities). Now I get it.
