I have read a little Discworld, and it was entertaining but I got a bit bored of the satire. I think it just ruins the immersion for me, to some extent. I honestly don't remember what it was that I read, or what book it was. I just remember it being Discworld because of the hype a friend in high school gave it, and I just couldn't keep myself interested in it. I guess I like taking my books seriously.

Two books I did read all the way through are The Soddit and Bored of the Rings, one which was alright and the other which was utter crap. I suspect Discworld would be better than both, but that's not enough to make me want to read the books.

I might like some other books out there like that Wheel of Time series, perhaps. Most of the books I read in the fantasy and sci-fi genre were lesser known ones, I suppose, but I've yet to come across anything that captures my favoured style better than Barclay's books (Raven/Elves ones, not Shout for the Newborn which was way too political for my tastes despite being a lovely idea for a book) or the world-immersion I got out of Tolkien's books.

EDIT: I also liked the Darksword trilogy but I didn't like the ending.
