I ran #Numenera
for the first time last night as a one shot. I found the rules easy to grasp and gameplay was quick. I think that the learning curve for the players was much more steep.
I used the "Beneath the Pyramid" scenario from the Weird Discoveries
adventure book. The basic setup is that a local rancher wants his giant mechanical bugs back after they're stolen away by a mysterious mist. The scenario suggests that the PCs could be in town to watch these creatures race and maybe even gamble a little bit.
Since the adventure is designed to be accommodating to change, I felt comfortable changing that setup to something more like the running of the bulls in Pamplona, Spain. It was a great tutorial mission. The players got to roll a lot, use effort, and I got to practice GM intrusions.
And actually, that's something I have to wonder about: how frequent should GM intrusions be? I don't think I used them nearly enough, because at times the game felt swingy. But, I didn't want to do an intrusion more that once per round. What have other Numenera GMs done in this instance?
