@irf23 Guards! Guards! is the best entry point to the City Watch series obvs, for the entire Discworld there is always The Colour of Magic which is neat but not the pinnacle of fiction, he was obviously still finding his footing. The entire Rincewind series is not that great imo. A standalone would serve well (like Small Gods, that one's great!), but otherwise I'd always recommend the other series, I'd probably start with Death (book 1 Mort), though the witches are great (book 1 Equal Rites iirc).

The watch series does get significantly better (I love Guards! Guards! but there are brighter gems in that series), Men At Arms, Feet of Clay and the Fifth Elephant are great and I consider Night Watch to be the single best Discworld book (it's insanely good). Thud! is amazing aswell. Most of these are crime with a little social study mixed in (except for Night Watch which is basically just a social study), there's a lot of character growth for Vimes and seeing the Watch build its footing is very rewarding. I'd give it another shot.
