The Chill 6: Gaming relevance - situation
I came to these books after Ron Edwards mentioned them in the supplement The Sorcerer's Soul. He recommended the situations as being one that are ripe for gaming goodness. I've had success basing campaigns on them. I get a stable of NPCs to use, and all of them have connections to each other and each has a goal and motivation for making things happen (or that things remain concealed). I'm involved in character generation and make sure to connect PCs to the relationship map.
Things generally go well! The last one I did was a Blue Rose game based on The Zebra-Striped Hearse, and that got all sorts of fun.
Have you used these sorts of relationship maps in your gaming? Have you used one drawn from a book or other source?
If you've not used R-maps, would you consider doing so in future?
