Fantasy should not include science fiction. It would be a list along the lines of:

- Tolkien
- CS Lewis
- Lloyd Alexander
- JK Rowling
- Robert Jordan - Wouldn't add this one, due to the poor characterization skills.

- George RR Martin
- Brandon Sanderson - OK, but as I said in your post, more of a "popcorn" level read

- Pratchett
- Pullman
- Mieville
- Erikson
- Goodkind - You're sadomasochistic, aren't you?
- Gaiman
- Farmer
- Bakker
- Eddison
- Moorcock
- Wolfe
- Zelazny
- Salvatore - Ummm...no
- Weis & Hickman - see above
- McCaffrey (collective vomit after the last three) - or maybe with the first three as well?
- Fritz Lieber - LEIBER
- Piers Anthony - Meh
- Clark Ashton Smith (largely only for Averoigne)
- Holdstock
- Gary Gygax (he wrote the Gord the Rogue series in addition to D&D modules and rulebooks) - Not what I'd consider to be the best written stuff out there, to say the least
- Lackey - Meh
- Guy Gavriel Kay
- Vance
- Eddings - Nah...
- Lewis Carroll (can't forget him!!!)

I'm sure I've forgotten a few, but those are the major fantasy writers I can think of.
