I am working on an Arneson style megadungeon

[Havard]

Well, maybe not a megadungeon, but we shall see how big I care to make it. Anyway I want it to have some nods to Arneson's design style. Probably I will make it closer to a traditional BECMI D&D type dungeon when it comes to placing monsters by room, and I am not sure I want to make all the corridors be 90' off the grid, but are there other things a true Arneson dungeon ought to include?
