Dune set the standard for most scifi
Lord of the Rings set the standard for most fantasy.
That's how it works. In the science fiction book world most books are awful but the ones that are good are really good, there's no in-between, so whenever we come across something that people, not only scifi lovers like, then we've found something that will set the standard for as long as the genre is popular (which it isn't, right now, because of all the crap that's out there).
Alas, I've found Enders Game, god I love this book. I started it late yesterday and I'm almost finished.
