You might want to change the subject from "New Poll" to "Favorite campaign setting" or similar. If you're looking for opinions, you might want to tell people the general topic.
My personal favourite would be the Kingdoms of Kalamar Capaign setting put out by Kenzer and Co. simply because it was the first setting I ever really picked up, read and made my own. Sure, I've made myself a few impromptu settings for a quick campaign, but Kalamar gave me something quite cool to work with and build upon.
At heart I'm a political junkie, so I dig the background stuff that is either directly or indirectly alluded to in the book. I regret, however, that I've only had the chance to run a single campaign so far...
It was basically a campaign that revolved around conflicts the Kingdom of Eldor was involved in... I introduced gunpowder of gnomish design and dwarven manufacture, and thereby annihilated the elven Realm of Lendelwood which held a great strategic resource value to the King of Eldor, Brenbol the First. Soon afterward, the PCs struck out on their own, and one began pushing the design of Final Fantasy-esque sky ships to the Kingdom of Cosdol (the most magically capable nation in the West).
This began a great arms race between Cosdol and Eldor. It culminated in the reunification of Mendarn, Cosdol and Eldor into Greater Brandobia.
It was a good campaign, in my opinion anyway, but I think I'll go back and make it that the airships were in fact more akin to zepplins without the hydrogen than they were FF-esque airships...
Further down the road, I intend to keep my timeline going, since I've all my notes from before, hehe.
Actually I'm rather sure Talindra wasn't even aware of the other poll, seeing as how this thread was originally posted in the D&D rules forum. Lighten up, I doubt anyone would make another poll just because they don't like KoK.
And I agree... assuming that this poll was started just because your favorite system was ahead (Not in the lead mind, just ahead of most) is sorta like a paranoid conspiracy theory...
