We have tags for different fantasy genres: low-fantasy, urban-fantasy, and well as magic for general fantasy questions, but what always struck me as odd is that we don't have a tag for high fantasy. Why so?
Tags are created on the fly, they're not preplanned under any sort of structure. Some people have used low-fantasy and urban-fantasy but not all that many in the grand scheme of things. If anyone with over 300 rep had wanted to use high-fantasy then it would exist.
