I am also kicking around the idea of discussing my weekly game preparation here. I feel like this is something that has value. To a new DM it is great to see what preparing a session involves. To a veteran DM it is always interesting to see how others do their prep work. Also a good thing for me, to be able to work through and to share the happenings of my campaigns. I run two games a week (Life in the Time of Giants and V.S. Giants) I plan to keep the discussions separate so if you are a player in one of my groups you should DEFINITELY NOT read your campaign’s prep notes.
