Who wants to leave out all the fantasy? Thats kind of the whole thing, the interaction of fantasy and mundane. Maybe the fixation on "gritty realism" is just the parts that are more easily discussed? I only vaguely grasp the more fantastical elements as it is, but certainly they would have to be included.
Seeing the world through the eyes of a someone with the Sight, or without, or the Cish, is another element that would be important, right?
