I stopped playing DnD when they came out with 3E.
I used to enjoy the fiction though. The Realms, not so much. And Drizzt's stories, well, Salvatore should have stopped them a long time back. It just went on and on. I always wanted Artemis to cut that self-righteous drow down.
I enjoyed Krynn more, but just Weiss and Hickman's work. I didn't care for the other stories much, especially the prequel stories for the companions.
Ravenloft... well, I recently read "I, Strahd" to my girlfriend. She liked it (surprised me) and I wound up reading the sequel with Azalin to her, as well as the one with Jander (Vampire of the Mists?).
Never much cared for Dark Sun and my only real exposure to Planescape was through the crpg, Torment.
My DnD days are long in my past but I still have most of the novels buried in box in the basement (as well as old character sheets and old 2E monster manuals and the first two Ravenloft boxsets). I get a tad nostalgic sometimes, and wish I could find a PnP group but it's largely just fond memories for me.
