How to Build a Megadungeon the Moldvay Way

The Dungeon Master Information section of Moldvay's Basic is an amazing resource for anyone wanting to build a megadungeon. It is, somehow, definitive in its own right. Tom suggests that dungeon creation should follow these six steps:

• Choose a Scenario;
• Decide on a Setting;
• Decide on Special Monsters to be Used;
• Draw the Map of the Dungeon;
• Stock the Dungeon;
• Filling in Final Details.

I plan to follow this list for each and every level, except for the fact that I would prefer to plan the special encounters before drawing the map, so that I can design some rooms by first thinking about what they will contain.
