You know, you’re not wrong.
Plus, the first three books can almost be considered to be…kinda sorta…seperate…ish…from the rest. Since Pratchett almost restarts certain characters over again. I mean, its still a lot of fun, but the way Colour of Magic/The Light Fantastic and Equal Rites end, don’t quite fit with the way the rest of the series goes.
However, we are talking about a flat world, on the back of four elephants, standing in a giant turtle that swims through space.
And the universe itself runs on Narrativism.
