Gotta spread some XP around... yadda yadda. I totally agree, only I spammed the poll.I didn't want to spam the poll so I didn't vote, but I would have said all of the above and more, except dungeons as a setting.
The question of setting and style presented here is sort of like asking whether I like Lovecraftian horror, raunchy black comedy, or high fantasy adventure. They're all good. I wouldn't want to limit myself to only one style.
Even within my last D&D campaign, I ran sessions that included little to no combat, and one that was mostly combat, some that were in the jungle and some in a big city and some in a farming village (and some in a desert). There was exploration, there was character exploration, and there was so much intrigue between numerous powerful groups it was hard to track; and that's just over 12 sessions. So, yeah. All of the above.
Somewhere between those two pairs is Military and Naval, not in the poll. Not quite the same as 'Combat Heavy' - big units and sometimes fleets. (Heroes of Battle remains one of my favorite 3.X books.)
The Auld Grump
Such enthusiasm for cities. Not sure GMs are getting enough medieval grit in there. Last place to go if you want to avoid the plague.
With the exception of an adventure that begins with: "<Party generates situation>", pretty much every adventure should have this structure. Even a hack-and-slash dungeon crawl should reveal something about the situation that allows the PCs to make an interesting decision about how to resolve the situation.
