It seems that I had quite a typical start on the Pratchett series. I also started with The Colours of Magic, went on with The Light Fantasticand then went on to Mort. I've read some more in the meantime but I have to say that I still love The Colours of Magic. May be this is because it's the book that hooked me. I even re-read it and enjoyed it more than the first time I read it because I took my time for laughing about all the puns and great one-liners. I really love the little imp and his nagging when he is running out of ink
And I also liked Death very much which is why I read Mort. I just loved it and cannot wait reading the next book in this row. So far, the little imp and Mort are my absolute favourites but as I do not know all yet, this might of course change...
