Gameblast17 was my first attempt at running a 24 hour RPG session. 24 hours, 24 dungeons (dungeon levels to be exact), at least that was the idea....
In fact I came up with the idea far too late in the day. Between writing the adventure and painting the minis and work, I was getting about 3 hours sleep a night for the final week or two. I had so little time left before the session, that I had the players cutting up my floorplans for me.Then there was the actual 24 hour session!
It was a lot of work!
I ran the adventure using The Black Hack, a minimalist RPG that looks a lot like original D&D, but actually plays in a quite a modern way.
The floorplans you can see below are from Inked Adventures.
