My wish list:
1. Fafhrd and The Gray Mouser. Just don't waste time with the later tales as they lacked the magic (no pun intended) of the earlier tales.
2. The Amber series (which was supposedly in development, but I haven't heard anything on it in a while).
3. The Champion Eternal cycle. In my ideal world, you'd have four series featuring Elric, Corum, Erekose and Hawkmoon running mostly concurrently. The Erekose series would feature that character assuming his various identities in other realities, more than what his trilogy and one graphic novel showed (when Quantum Leap premiered, my first thought was of the Erekose stories). Naturally the whole thing would end with Hawkmoon and the Quest For Tanelorn.
4. The tales of Silver John. Love the shit out of these stories, especially the short stories in "Who Fears The Devil".
5. The Dying Earth. Crazy far flung magical adventures in the millionth or so century? Count me in.
6. Zothique cycle. The tales that inspired the Dying Earth, though more "Lovecraftian and macabre adventures in the millionth century" than the latter series.
7. The Silmarillion. I'd read all of the above before I'd read Tolkien, they were my introduction to fantasy. In the years since I've come to really appreciate Tolkien, especially the Silmarillion, my favorite of his works.
And of course.......
8. The Lensman series. Update it where needed, keep it retro where not. Full blown space opera at it's best by anyone not named Edmond Hamilton.
