I am building my own fantasy world, and the thing is, there is not much fantasy. I want the world to be similar to ours; similar climate, species, physics, etc., but the geography is obviously laid out differently. I want the story to be as realistic as possible, being able to explain every "magical" thing that might happen, and focus strongly on the characters and their conflicts. The thing is, I have what I think is a pretty good plot, but eventually it seems to trail off into simply the conflict of one central protagonist and becomes a coming-of-age story about him. Is this enough? Does the fantasy world need a huge, all-encompassing, world-ending conflict in order to be compelling?
