Once I stopped having the mental picture of the Death of the Discworld out of my mind when the story got to the point where death showed up, I was able to get into it better. Having listened to at least 5 Discworld books in just a few days, I had it imprinted in my mind.
I think I will quite enjoy PodCastle. I've never been a huge fantasy fan, though Tolkien has always been enjoyed, I am glad to be able to hear more. I listen to podcasts all day at work, so variety is great! I'll soon catch up in the archives, so I'll need more sources to keep a full plate of ear food.
Going back to my first point, I think listening to other possibilities can really expand the way we think, because we can easilly get set in a way, and even something that is not reality can change how we view reality.
