Fantasy novel reccomendations

I'm pretty sure I like fantasy, it's just I've never actually read much of it. I loved The Lord of the Rings, I preferred the Silmarillion. I'm currently half way through The Children of Húrin and like it too. I've also read every single Discworld novel, although I've felt the last few were declining in quality. Maybe I'm just personally bored with them. Anyway my point is, that's pretty much all the fantasy I've ever read. So what classics am I missing?

Also a related, much more specific question: I've become a fan of the D&D setting Planescape after playing the game Planescape: Torment. Are there any novels set in a similar fantasy world?

#10, you DO realize that you're posting on 4chan, right?  What icon of the Queen's English were you expecting to encounter?

Jordan's not the only metahomo around here.  {holds up a mirror}  Look like someone you know, you fucking queer?

JORDAN IS NOT "DECENT".  You may as well read Kevin Anderson, either before or after he mouthraped Frank Herbert's paper-dry corpse.  Jordan can carry you only so far, and then you have to set him aside as being a "phase" of your literary life.  Since you have access to better authors, you should seek them out forthwith!  There's no need to hang with the litqueers.

For your punishment, Fag#10, go re-read the "Sword of Shannara".  Popular fiction becomes a tsunami of bad literature that we must constantly be on our guard against, lest the general public start to think that THAT dross is "normal".
