The thing that turned me off is the fake british accents people seem to feel are necessary. It's a fantasy world, who's to say what kind of accent they have??
in my current game, the dwarves all have redneck accents, and if anyone questions why they're not talking in bad Scottish accents, they start talking about "ijits" who've never seen a real dwarf but only halflings dressed in fat-suits at the minstrel shows pretending to be dwarves...
