Which do you prefer? Lurid, fruity prose, awash in imagery and sensuous textures and colors? Or straight-forward, clean, simple prose?
(You thought I was going to ask something else, didn’t you? Admit it!)
Honestly, it depends on the book and how far the author goes with it. I like world-building (I read a good bit of sf and fantasy) and I enjoy when an author uses language and words to create and set-up the world and atmosphere. However, it can be something that is overused, especially within the realm of fantasy. One of my biggest criticisms of Tolkein and all his imitators is that we can get so lost in the description of the world that we often we lose the reason I’m reading the story in the first place–the plot. I do think that you can find a good balance between giving the reader enough detail to create the world and fill in minor details in their own mind and between an excess of wordage where it goes on and on and on for no good reason.
