John Harper (author of Agon) is playing in a Spirit of the Century game and hacking in some things that I really find useful and interesting. over at The Mighty Atom: SotC Hack is a post about tweaking the Stress/Consequences bars to make Consequences happen more and generally speed up combats a bit. It’s a direct yoink from the upcoming Dresden Files rules.
Actually, he’s got quite a few insightful SotC tweaks discussed over there (and Fred Hicks is conferring with him in the comments), so it’s worth checking the whole thing out: The Mighty Atom.
