Friday isn't my regular game night, but I had some company--someone who has regularly appeared as a "guest star" in many of my home games, and with a free evening we decided to do something fun and different: let my son, Mac, get behind the GM screen. Mac had been wanting to GM for a while, but had been nervous about it, especially in front of the regular gaming group. He had, however, picked up a free module from Mythmere Games for their Swords & Wizardry RPG.
It's a fairly straightforward story: a village is destroyed, a hidden lair revealed, and the PC's go in to clean house. There's some cause-effect elements where you can easily die through player stupidity, some simple problem solving, etc. And there's four pre-generated PC's. Mac was clearly glad to be running a game for the visiting guest, his sister, and me, and he did a good job. I helped with some rules issues, but many times I told him the OSR creed: you're the GM, just make a call.
So like I said, he did pretty well and we all had a lot of fun, which in the end is what this hobby is really about.
