I just thought of another thing:
Fantasy = LOTR-Ripoff (while LOTR basically is also just a ripoff of most of the western mythology)
I mean: Seriously? "Fantasy" means we're in a world, where things aren't like in our own. Where practically everything is possible, because it's friggin' FANTASY! And still writers (be it of books, films, TV-Series or games) think that if it is set in a "Fantasy-World" we need dragons and dwarfs and elves and trolls and goblins and orcs and what-do-I-know. It's like every Scifi-Universe would involve Klingons and Vulcans.
What bugs me most about this, is that the writers show how lazy they are, because all of these races already are archetypes the reader/viewer/player is familiar with. Orcs? Stupid, but very strong. Elves? Wise, often talented in magic, but not very endurable. Dwarfs? Hard-working, loud, small (duh), often with a beard. The problem here is, that the writers don't need to think of their own world with its own inhabitants and their own behaviors. And that's just lazy. I'm not saying that stories that do this are all bad (especially because almost every fantasy story would be bad in that case), but it gets boring...
You know what I want to see? A serious fantasy story (meaning not a parody like Discworld) that uses these established races, but not their stereotypes. Dwarfs as a sophisticated society of magic users, elves as cunning, opportunistic rogues...that would be interesting!
EDIT: Oh, someone already covered that while I was typing. It's still stupid.
