Zelazny is great. I picked up his amber anthology and blew through all of them in a few days. Great old stuff.
Still, nothing comes close to Martin, though I suppose Zelazny actually comes close, or I should say, Martin went even more hard core than Zelazny. Nothing is held sacred in Martin's story. I don't think Gibson or Dick hold a candle to how utterly ruthless and demanding Martin can be to his characters
Read it, you'll understand
He breaks some VERY major fantasy conventions.
Heinlein is a wacko! Ok, I admit I still read all but 1 or 2 of his books
His philosophy is screwed up. Killing yourself and having your followers make stew out of you is not my cup of tea. That's communion I can do without!
Jordan's best book in his WoT series is the first one, by far. It was all downhill since there, but you have to read them because you need to finish the damn story! ARRGH!!
I never met Ursula Le Guin, but I did have her daughter as a guest speaker for my early opera class. I might take her rennaissance/baroque music class next quarter if I have spare time.
