I have read a lot about megadungeons over the last week or so, and the more I read the more I want to run one. I have never run a megadungeon before. In fact I hardly ever run dungeons at all. I can think of two real, multisession dungeons I have run. The most recent was the 4th edition module Keep on the Shadowfell. This combined two things I am usually wary of doing in a game: a pregenerated module and a dungeon crawl. It was one of the worst modules I have ever read,let alone ran. We made it maybe 4 sessions in before going back to Traveller. The first dungeon run I did was shortly after high school. We had been playing for around 8-10 years at this point and I put one into a long running campaign purely because we had never done one before. It took about three long sessions to run through the dungeon and many great and memorable stories game out of that adventure. So this one was overall very positive. Generally my players pretend to be in the political thick of things, even at low...
