I think it is just our lack of stories such as these...the ones who attempt the style either end up trying to tackle very complex concepts and hence bore the reader to tears or take on alien world/earth in the possible future/or multiple dimension theme...so we try to match influences to the most apparent example we have...LOTR...Terry Pratchett is one of my very favs...i just wait to read the often quirky and amusing footnotes...
anyways have you submitted your novel to publishers as yet?
