I would like to relay I'm interesting development that occurred while I was running Greg Gillespie's
Highfell last night.
If you are not familiar, Highfell: the Drifting Dungeon is the second of Greg Gillespie's old- school mega-dungeons. These are huge, sprawling environments with hundreds of rooms, peppered with puzzles, traps, both classic and weird monsters, and bizarre, over-the-top factions. Highfell is a floating island that was once a college of wizards. It's made up of a collection of towers, many of which have single-floor dungeons beneath them, with the dungeon's "level" set more by the towers' distance from the center of the island then by its depth underground.
I am running as vanilla an AD&D1e game as I can; 50% of the play time has been dedicated to traditional dungeon crawling, complete with regular wandering monster rolls. My only house rules are that I'm using the B/X versions of morale and NPC reactions because they are just quicker for me to use from memory.
During their exploration of the
Crumbling Collegium of Kalguumer, a sprawling 55 room dungeon filled with secret doors and pit traps, the player characters literally kicked off s bizarre chain-reaction.
