You might know this already, but the original series in that universe, The Riftwar Saga, Feist wrote about a DnD campaign he played with his friends. I picked up the first one, Magician, and it felt just like a DnD campaign, so I looked it up and sure enough it was exactly that.

I'm making my way through all of the books and haven't gotten to the Krondor books, so I don't know how different they are as I could clearly see his growth as a writer in just the first series. I'm currently reading through the Daughter of the Empire series that he co-wrote with another author and I'm really enjoying it.
