Of special note is the section in Empire of the Petal Throne relating to "Saturday Night Specials," pg. 100:
"Here too, the role of the "Saturday Night Special" cannot be overemphasized. Aside from the deliberately or randomly determined "normal" contents of Underworld areas, it is interesting to develop large complexes inhabited by special beings. These should have special histories, and players should hear legends of their existence on the surface. Their abilities and treasures should be individually devised, since these add interest and spice to the game..."
Not only is this rock-solid advice for classic megadungeon construction, but I particularly an enamored by the usage of technical dungeon design term of "Saturday Night Special."
