I voted for Greyhawk (although the LGG was good, so I could do without this one), Spelljammer, Dark Sun, Mystara (which includes Hollow World and Red Steel, which I did not vote for as they don't really deserve their own book imho--shame on you for listing these two sub-Mystaran settings separately but not listing Al-Qadim separately!), Birthright, and Other with Planescape and Al-Qadim in mind. I like mining campaign settings for ideas, and one-shot books make it easier for me to accumulate a variety of them without the cost of supporting an ongoing product line (so while I never bought a pre-3E Dark Sun, Mystara, or Birthright product as my limited gaming funds were going elsewhere, I'd snatch up one-shots of these in a heartbeat, especially with the old .pdfs available as further resources).
