I thought I had already posted here earlier, but couldn't find my post, so here goes.

Judges Guild Wilderlands. The first published setting for D&D and still the largest with eighteen 22"x34 Campaign maps. Doubled, because there are incomplete players map, as well as complete GMs maps that comes in every Wilderlands module. My absolute favorite go-to for any original D&D games.

Greyhawk. This was the first TSR campaign setting that I first bought in 1984. I only ran games in it a few times, But Darlene's map was one of the best I had ever seen. I still much preferred my own homebrew settings, but liked the Chivalric orders and Heraldry that was a part of Greyhawk, so I totally and irrevererently added my own noble houses. I don't own anything from Greyhawk right now, except for all four of the gigantic campaign maps that came in the issues of Dragon Magazine right at the beginning of the 3e era., oh, and because Quag Keep by Andre Norton!!!

Aihrde. Been supporting Stephen and Davis since the day they opened their first booth at GenCon. Airdhe has always been a provocative and untamed setting, with a long history of bloody wars, so it is really easy to add in my own ruins and adventures.

Eberron. Campaign setting designed by a gamer, and published by WOTC. Very good quality with many original ideas. I have the entire setting except for the Eberron Player's Guide (which sucked hard) and Dragons of Eberron, because the basics were good enough for me to extrapolate and I created my own non-canon Dragonmarked houses so didn't need the add-ons provided in either of these books.

Also picked up the Morningstar campaign guide by R. Scott Kennan published by Joe at Goodman Games as of the semi-finalists. I actually wanted to get all three of the WOTC Campaign Setting finalists Campaign Settings but the finalists sold their settings to WOTC and the settings haven't been seen since, because WOTC ...quashing the competition, duh! Of the other semi-finalists two published, and are available, although I wasn't inclined to buy Dawnforge when I saw it at GenCon. Anyone else familiar with these and care to comment?;

There was also
Cappedocio by Alexandre Gélinas and two others (not published)
and Reign of Ashes by MissHappen at EN World (not published)

Three of the semi-finalists chose to forever remain anonymous, which is a shame, because these represent the best ten campaign settings out of over two thousand submitted for consideration.

Forgotten Realms is just really good quality by Ed Greenwood, and I finally got around to getting the 3e Forgotten Realms Campaign Guide in 2007, and have been slowly collecting FR books since. Currently have Shining South, Serpent Kingdoms, Silver Marches, and Unapproachable East. I have run about three or four FR games over the last four years.

GURPS: Alpha Centauri. The only time I ever bought an RPG that was originally a videogame. I like to create scenarios and adventures by playing about fifty turns or so of the videogame and then using one of the factions as the base of operations for an adventure. This is an acquired taste, and I don't have many opportunities to run games for this. have not run a game since about 2010.

Mindjammer My current Sci-Fi favorite. Just bought the book this spring, and haven't yet had an opportunity to run a game, but have been spending time setting up for a trans-human campaign in the Fringe Worlds.

App! Almost forgot, Gamma World. Except, what I have for this is not exactly a published setting, just a big collection of homebrew campaign settings, Including Colorado, California, Florida, and the newest region set in Texas, that I just did up today for this game.

Traveller's Third Imperuim and the short lived New Era 1248. Because.
Shadowrun setting.
Stars without Number because favorite sandbox.
Mutant Future because with the right rolls you can be a floating Octopus.

Shadowrun, Spelljammer, Star*Drive.
Not really an RPG setting, but I love the Mushroom Kingdom for RPGs.

I liked new era OK and even think it needs a reboot.. This time there should be at. Least a few stable,  sane AIs willing to work with biological lifeforms.

Serious Question Time: Why don't you just run a game of New Era and, like, PUT stable, sane AIs into the setting yourself?  Why do you need a reboot for something that... small?

Glorantha
Hyborian age
Middle Earth

(in that order)

Haha thats neat. I love Sid Meier Alpha Centauri and would love to play in a setup like that. Unfortunately it's hard to find players for it.

I hate sister Miriam with a passion.

Is it like Civilization in space? And was it ever a boardgame?

Hmm, let's see.

• Greyhawk - I like the scope of the folio and the original boxed set: broad strokes with enough detail to spur your imagination, but not *too* much detail. Awesome Darlene maps. Yeah, it's "vanilla RPG fantasy world" in some ways, but it's done well and has a cool feel to it that I like.
  
• Wilderlands - Again, lots of cool maps and bits to spark interest. I also like the whole campaign hex system (which is nicely summarized in the JG Ready Ref sheet book). My biggest gripe with the Wilderlands is that there are too many NPCs with classes and high levels in odd places (and too many powerful monsters in odd places) for my taste. That's easily remedied, though.
  
• The Fantasy Earth in RMIII - I like to read history, and I like some historical elements in my games, so this was right up my alley. I know a lot of RQ gamers were annoyed by the removal of Glorantha, but I'm one of the minority that liked this approach better.
  
• Monster Island - I think this is a way cool mini campaign setting with tons of pulp and swords-n-sorcery influence. Again, right up my alley.
  
• Mythic Iceland - Another "fantasy earth" kind of setting, which I am a sucker for, and a very nice, well done book. My only real complaint is that I'd liked to have seen a small section in more detail, as a starting point to help you get rolling. (In Greyhawk, modules tended to fill this need.)
  
• The Morrow Project Earth - Post-apocalyptic "after the bombs" Earth. I thought MP had a cool way for the GM to approach this (using a road atlas and marking it up using target and warhead data/tables from the rulebook to determine the setting). I set my game in my home state, of course, after nuking the hell out of it.
  
• Hyperborea - From Astonishing Swordsmen & Sorcerers of Hyperborea. The setting and modules is cool, with "imported" Earth cultures and a neat setup. The modules for Hyperborea are well done, too.
  

There're probably others, but those are the ones that popped in my head, first. Honorable mentions go to I.C.E. Middle Earth (I especially liked the Northern Mirkwood and Court of Ardor sourcebooks) and to the Young Kingdoms (Chaosium Stormbringer/Elric/etc), and to the Lankhmar sourcebook released for 1e AD&D. I also thought Empire of the Petal Throne was really cool and interesting, but in my case I mostly liked reading about it, rather than running a game in it.
