This thought process came to me today while listening to the audio book of Neil Gaiman's Anansi Boys.
There are two kinds of stories. I don't have names for them, but Anansi Boys and everything else I've read by Neil Gaiman bar Neverwhere is the first type. It's the kind of book I'll burn through in one sitting just to get to the ending and then I'll never read it again because the whole story is about the ending, the twist, or what will go wrong.
The second kind is like The Dresden Files or War of The Flowers or The Wheel of Time. It's the kind of story where you don't care about the ending, you want the story to go and go and go and go, where you could live that story for the rest of your life and love it every step of the way.
Which do you prefer to write. How do you get that second feeling? How do you get the first? I think it has to do with worldbuilding, but telling Anansi Boys and American Gods from The Dresden Files worldwise is difficult, the differences are minor. Character is involved too, but I hesitate to say Neil Gaiman's characters are weak, because they aren't.
