....aaaaaaand now there's a new GURPS-related post on
The Collaborative Gamer.
This post is about Matt Rigsby's idea of "N" (from DF Adventures 1: Mirror of the Fire Demon), as compared with Christopher Rice's idea of "CER" (Challenge Effectiveness Rating, from "It's a Threat!" in Pyramid 3/77: Combat).
I also throw my own (much tattier) hat into the ring by introducing the vaguely similar idea I use: "Peril Rating." It's a bit like B.A.D. from GURPS Action, but for DF, and with a few extra adjustments.
Enjoy!
