GoT is porn based (not just “sex” porn of course, but “torture porn”, “war porn” etc.–the glorification of a particular visceral act not for the sake of story, but for the sake of pleasure) I think, but see all of the other posts I’ve written about GoT for more of my thoughts on that.
But I’m not looking to be GoT popular–I want to write what I want to write. A small, dedicated audience would be much more appreciated from my perspective than vast popularity. I’m not looking for some way to break into the mainstream–I just want to write the stories that I’d like to see in the world, and share them with whoever may be interested in them.
