I just tightened up the list a bit.
Lots of good suggestions here, but I say we focus on what I have in the OP for the meantime.
I think if we cut long cycles to 3 books, then we could have an easier time adding to the list.
As noted, this is not a definitive list. If anything, this is a survey—or maybe just a sample—of epic/high fantasy. It's a big genre with a lot of books, and so I can't hope to put everything up here to cover.
Consider that I haven't added such offshoots as sword & sorcery, low fantasy, urban fantasy, dark fantasy, or humor books such as Pratchett. I think keeping the focus on epic/high fantasy will allow us to explore what makes up the lion's share of the genre. If, after we've gone through what's currently in the OP, we have the desire to move into these subgenres, perhaps it will be then that we do. Those books by
China Miéville keep staring at me.
