Here and there I've been hearing about what readers 'expect' from certain genres. Romance readers expect the hero and heroine to wind up together. Fantasy readers expect epic fantasy full of battles and otherworldly creatures. Mystery/detective readers expect an element of, well, mystery, and a satisfying ending in which the mystery is solved.
Despite the fact that I just rattled off that list, it has occurred to me that I don't really know the full scope of what readers expect from standard genre fiction. I'd like to know this, otherwise I might fail to deliver what was expected, resulting in an unsatisfied reader.
What do readers expect from a fantasy novel?
Note: I plan on splitting this question up into several, one for sci-fi, one for mystery, etc. If you think I should just ask about all genres in one question, let me know and I'll edit this one.
