Some time ago, John was talking about the possibility of a sort of "sandbox" game world in which one-off and similar games could be set. I'm thinking about starting an ongoing generic fantasy game to be run on game days. What I had in mind is stand-alone scenarios using the Swords & Wizardry rules (with personal tweaks to make it a bit closer to the old Red Box D&D). No ongoing commitment would be necessary for anyone, and I would just announce if I had a scenario ready for a game day and ask for interested people to bring a character - or make one on the day, since making one takes about 5 minutes!
My current scenario isn't explicitly set in any setting, but if people were interested in participating on both sides of the equation (both as players and as DMs in a sandbox-type world) then I would maybe try to pick a location in the generic world John has a website/blog for.
So, is anyone interested in (occasionally) participating in something like this?
