Hey, Gary

!
I come bearing a question re: the mechanics and cosmology of the planes in OAD&D, specifically with regard to how the manner in which they've been treated by divers designers in numerous products.
Initially (earliest appearances in
The Dragon, the
PHB, Kuntz and Ward's
Deities and Demigods) there's little mechanical information--some notes on the multi-planar existence of demons, undead, powerful swords, et al, and some light flavour references and text (the cover of the first printing
DMG, with the City of Brass over a burning sea of lava, a few references in
MMII to what certain layers of the Abyss look like, and so on). As time marches on we have modules like Q1 (
'Demon Web Pits) and Roger Moore's articles on the Astral Plane in
Dragon were we get a slew of detailed mechanics, and some interesting flavour developments (Int and Wis acting as Str and Dex). By the time of the
Manual of the Planes we have some very specific and detailed information on how exactly things work in the planes, and what, in particular, they "look" like. Places like the Ethereal Plane and the Plane of Elemental Fire, particularly, are described in quite a different manner than what we got initially.
My question is this, was this eventual development of the planes, mechanically and descriptively, in concert with what you envisioned (in terms of play and setting), or is it the end result of several smiths distilling a brew, which, while palatable and enjoyed by many, is ultimately not what "your recipe" called for?
(I believe I know your answer to this, likely from some other board in time and space, but I ask it again in order to have clarification for several here who seem interested. Also, I've tried to avoid "leading" you one way or another.

)
As always, your time and answers are most appreciated.
