I'd have to say Forgotten Realms and Planescape are my favs...  they tend to be the most epic, and usually the most well written.  Dark Sun had some very great concepts, but I never managed to find a group to play with.  Always felt Dragonlance was a great novel world, but the game products were sorely lacking in quality.  Mystara was a horrible mishmash of a make-it-up-as-we-go-along world, and it showed.  And believe it or not, I'm not really a huge Greyhawk fan (sorry Grodog)...  alot of the stuff was too inconsistent (esp. in 2e), and it has NO 3e support, other than Living Greyhawk, and to this day I'm totally confused as to WHY WotC insists on using it as the standard 3e world.  I like the flavor of the old generic stuff though.  Ravenloft too had some interesting concepts, but I've YET to find somebody that could DM it with the correct atmosphere.

In the 90s I've been DMing a Dark Sun campaign for two years or so... great stuff! Also the novels were high quality. I like the Spelljammer concept, it's just too weird. I'm planning to introduce it to my current campaign (hopefully none of my players ever read this). The bad thing about playing & collecting is that you have to get doubles for all of the playing materials  

Well Faorite is Greyhawk, I simply like the way it felt there was enough to it to keep you interested yet vague enough to allow you to actually do whatever you wnated with it and make the changes.



The changes each person I knew made to their own Campaign pretty much allowed there changes to fit into my world also. I also went and made a world map of the west unmapped portion of greyhawk, and then fleshed it out in detail the way greyhawk was done. Downfall no one was into playing much by the time I did this, so it has sat in dust for about 13 years with nothing ever done with it.



As far as second favorite I will accept Forgotten Realms, it has a nice feel to it I just never really liked this too much. The rest lets say I Hate them ,and well I have found no one else really likes them either as far as to purchase them so I have even given up stocking or purchasing the items.



With exception to planescape it does sell as has been pointed out to me, I just will not take chances as I do not know enough about it to be a credible seller of the items.

Hey NDH, your 13-year-old project is quite topical!  There's been a lot of discussion on Greytalk and Canonfire! about the western portions of Oerik, off of the old Darlene maps.  Give some thought to submitting an article to CF! or to the Oerth Journal!

I also thought that the Spelljammer concept was pretty good (Roger Dean and Rodney Matthews works fit well as inspirations), but I never really did much with it.

Well I'll be a dissenter and say I liked DragonLance.

Had some great fun playing and DMing the modules.

Never actually got through them tho...

Greyhawk.  I stopped actively playing before FR stuff came out.



I buy some of the new stuff, always the new rulebooks.  I buy any FR stuff that has to do with the Underdark and the Drow (that were stolen from GH).
