Okay, second try- here's the pol for those of us over 25. I've included all the authors mentioned by posters in the other thread and a few gaming-specific ones (who here read Gord?)
For the record, I've read a little more than I voted on. I've read Leiber, for example, but I just didn't care enough to read anything more than the short story I found in my dad's old books in the basement. I only checked the boxes of people I've read and whom I might read again.
He was on my first list and I forgot to paste his name in- yeah, I've read several of his. I have Troy: Shield of Thunder on my desk right now, waiting to be read. Probably one of the more glaring omissions.
You're missing Gene Wolfe, author of, among other things, The Book of the New Sun, which is one of the best fantasy sequences (unless it's really SF), ever written.
Also, I'm newly 40 and have read works by most of the list.
