When you have a poll with multiple choices like this, and none of the choices particularly stand out from any of the other choices, that means that none of the choices are particularly appealing. Sure, Dark Sun and Planescape might be more appealing than, say, Dragonlance, but, again, that's just a RELATIVE standing. I mean, according to that poll, Planescape should come out before Dark Sun, right?
It could just as easily mean all of them are very appealing. I know that I would have voted for nearly all of them.
