+Tim Shorts, +Chris C. and I have been doing some round-robin GMing with a shared world. It has been a good time. Here is a bit more about what have been doing in bullet point form:
- Using a Simple Rule Set: We are using Pits & Perils and it has been serving us well.
- Keeping the Group Small: This was a hard one for us, but we had decided to restrict our group to just the three of us. We had been talking about this style of play for several months and decided that it would work best with the three of us. As far as gaming goes, it was the right decision. Personally and socially, it was difficult thing to do.
- Short Adventure Arcs: We have been rotating the GMing duties every 2-4 sessions. Each time, whoever is GMing starts a new arc for the next 2-4 sessions.
- Not Quite a Sandbox: Each adventure arc has started with a specific problem to solve or task to complete. Rather than spending time with the players figuring out what the characters are going to do, each arc has started a bit more railroady. Sometimes it is as simple as an NPC asking for help (we have all used this at least once). Other times, the PCs travel into a village with a major problem to be solved. We made a conscious decision to start off each adventure arc with a specific task or goal.
- Not Much World Building: We have not done much world building, except what was needed to support each adventure arc. The minimal world building was not intentional but I think it has worked fine so far.
- Same Characters: Each of has been using the same player character throughout. When one of us is GMing, the GM's character simply sits out those sessions.
