How many official settings have there been?

[Echohawk]

What about Sovereign Press/Margaret Weiss Productions (Dragonlance) White Wolf/Swords & Sorcery/Arthaus (Ravenloft) or Alderac Entertainment Group (Oriental Adventures/Rokugan)? Those were all produced under licence.

They were d20 products and not D&D products, since their license didn't allow them to use the Dungeons & Dragons name, though.

Once the d20/OGL licenses started the only way to differentiate between the two is by the logo. Kenzer was the only 3rd party allowed to use it after the licenses were released (assuming you count Paizo's publishing Dragon & Dungeon as "something else." WotC has been very protective of the brand.

If you start counting all d20 settings then you'll have a very, very, very long list.

How about Averoigne from the module X2 Castle Amber?

Averoigne is part of Masque of the Red Death i.e. Gothic Earth.

Part of my inspiration here was Roger E. Moore's article Chronomancy and the Multiverse, which explicitly says that the Masque of the Red Death setting is the same as Averoigne from Castle Amber/Clark Ashton Smith, and suggests Murlynd has visited it.

...quoted from this most excellent thread by rip about Oerth's parallel worlds Uerth/Aerth/Earth/Yarth.

Masque of the Red Death

Pretty sure this was intended as a setting.

Don't forget "Hollow World". I love using that map for all my campaigns.

Technically the Hollow World is part of Mystara/"The Known World." It depends on how you count sub-settings.

Masque of the Red Death

Pretty sure this was intended as a setting.

Never having owned it or even looked at it (as was the case with a lot of the items on the list) I relied upon the explanations of others as to how to classify it. If I have it down as "not intended as a setting" then it's because people who knew something about it told me it wasn't for whatever reasons. In this case I believe because it was an expansion of rules for Ravenloft, not a setting unto itself. As I said, though, I don't have first-hand knowledge of it.

It is a fine point that came up with a number of the listings - what was it intended to be, and what was it actually treated as and thought of as. It's why I added the category of "honorable mention". Even though TSR/WotC may not have genuinely intended something as a setting unto itself, several items on the list still came close to being one. MotRD would be one of those, but the list was supposed to be ONLY settings that were OFFICIAL TSR/WotC releases and were intended AS settings (and what the OP asked for).

Wasn't that pretty well incorporated in the Known World even in the early days of the setting?
