High-Fantasy... of course
I have played D&D since '82 (cripes... that's 22 years!) and have played NWN since it first hit the shelves. I have tried other pen and paper RPGs but none of them have the same connection that a high-fantasy game does. Perhaps it's because that was the first RPG I played... perhaps it's because fantasy is a mixture of mytholocial history and romantic fantasy that most everybody can related to. But it is obvious (by game sales and your own poll) that high-fantasy is the preferred genera.
