So, what would you call Snarfquest then?
It had time traveling evil wizards on Harleys, a robot paladin type that got a Knight Order to emulate him, a dragon's head ventilated by a .45 magnum, and starships. Also elves, female humans in chain mail bikinis, medieval kings, and spoiled princesses.
Ah, I loved Snarfquest.
Anyway its not the content that makes a story/movie science fiction or fantasy, it is the thematic tone in which it is portrayed that determines genre. Star Wars is Fantasy.
