I personally don't like discworld so much, I've read only a little of it mind you but I just find it borrows ideas from too many places, I did find one of the games quite amusing though.
Oh and I don't know if it counts but the Dark Tower books by Stephen King were an amazing read for me and of course the LOTR and the Hobbit were great although I found them a tad long winded in places.
Warhammer fantasy novels are brilliant!
I've heard this from plenty of places so I'm thinking of looking into them. Although I'm not sure if I should be looking at the more Warhammer stuff or the 40k stuff, any advice anyone?
Again another set of books I'm not sure if really fit into fantasy, these ones seem to be a rather loose fit into the genre especially but the Vampire chronicles were a fun read.. although the last load weren't so great.
