I know, and the Science Fantasy category doesn't even include Star Wars, arguably the most well-known science fantasy of them all. In truth, you could argue that most science fiction is in fact science fantasy, and many bookstores include science fiction in the fantasy section. But in defense of Jane, she did specify books, not movies.
Also, many of these categories bleed into each other. Harry Potter, for instance, is both Contemporary Fantasy and High Fantasy.
Other examples of science fantasy:
the John Carter series
Terry Brooks' Shannara
Dragon Ball Z
More Low Fantasy:
The Green Mile
Preacher (wow, a map based on Preacher? Sign me up!)
A Song of Fire and Ice is actually High Fantasy, not Low Fantasy. It has dragons and supernatural entities, for one thing. Low fantasy is primarily set in the "real world," whatever that entails, while high fantasy takes place in a completely fictional world with its own laws of physics.
Other high fantasy works:
The Northern Lights
The Chronicles of Narnia
Dungeons and Dragons
Wheel of Time
The Dark Tower (elements of the supernatural, magic)
Harry Potter (yes, it takes place in the contemporary world, but most of the action takes place in the wizarding world, which is definitely High Fantasy - wizards, dragons, mythological beasts, etc.)
Alice in Wonderland
The Black Company (yes, it's dark, but it's in a different world with its own rules)
For Contemporary Fantasy, you could have things like
The Dresden Files
Thor (high fantasy as well)
Hellboy (as Lovecraftian as comics get, so dark fantasy, too)
Harry Potter (fits here, too)
Lewis' That Hideous Strength
Mary Poppins (hah!)
His Dark Materials (again)
more Dark Fantasy:
The Dark Tower
the Elric books
The Black Company
So don't despair! High Fantasy is a broad enough category to contain many different types of maps.
