Dont know if it is just me who didn't know, but I had started the Discworld series with the new rerecordings, but I DNFd because the narrator just grinded my gears.
Someone told me to listen to the older original recordings, and they just hit the tone and humor so much better. I finished Small Gods, Guards! Guards! and Mort in 2 weeks and had a blast every part of the way.
They're kinda old so the quality is lower and there is some quirky audio at chapter transitions, but it is still so wholly worth it.
If you're looking for them, they're the ones read by Stephen Briggs and Nigel Planer.
