I was reminiscing about one of my favorite dungeon experiences today.
The first time I ever played Tunnels and Trolls, I was a participant in an adventure called "The Dungeon of the Bear."
I only remember it in "images". I remember that there were trolls with crossbows in giant violin cases. I seem to remember a forcefield holding the ceiling up on a room.
I remember being turned into a badger, by the infamous "Badger Diamond".
Dungeon adventures should be filled with delightful impossibilities, puzzles and treasures.
I don't care if the dragon IS stuck in the room. I don't care if the orcs have no food source. I don't care if the trolls live right next door to the zombies.
Dungeon adventures should be fun and mysterious. Period.
Sometime in the future I'll reminisce about "Bellicose Keep"!
