I really enjoyed this, my introduction to Pratchett, and have now decided I'd like to read the whole Discworld series.
There were times during reading that I thought it was going to get all dry and philosophical, but fortunately, the author never took things fully in that direction. And those philosophical discussions would instead take some kind of wacky turn. The writing style seems genuinely British, and the satire is more subdued than say, Christopher Moore's style.
I enjoyed Rincewind's character, and look forward to finding out what becomes of him and Twoflower (and the Luggage) in The Light Fantastic.
