I am about to perform two gaming related activities for the very first time this morning.
1. Run an adventure module which I bought rather than writing myself.
2. Run an adventure written by James Raggi.
Seriously, I've never run a pre-written module before, ever! (Actually, thinking about it, I seem to remember running the sample adventure in the Mentzer basic set... but apart from that.)
It's also going to be the first session of D&D (well, Labyrinth Lord) I've ever run where the PCs have firearms.
I shall post a report of how it went later...
