It puzzles me when people complain that there isn't enough variety in the fantasy genre when I have no problem finding books that take place in all sorts of settings and with all kinds of premises. It does help, I think, if one doesn't limit oneself to authors of one gender and books for one age group, because a lot of the variety I am seeing is admittedly sold as YA (though with some rather mature themes, and by mature I don't mean sexual but serious and relevant) and/or with main characters who are female, which I know a lot of men automatically avoid. People choose what they want to read, as is their right, but by instinctively turning always toward the familiar they do limit their chances of finding something fresh and new. There is lots and lots that is new out there. I don't say that all of it appeals to me personally, but when a book disappoints me it is seldom because it lacks originality. More often it is something lacking in the characters.
What I would like to see more of and what the fantasy genre actually needs may be two different things, since the world does not (alas) revolve around my personal tastes, but if it was up to me, I'd like to see more character development combined with superior worldbuilding and fresh premises.
