Are you satisfied with your work? (Score 1)

I had read a number of your Xanth novels, and found them very light and enjoyable, when I stumbled upon your early novel Macroscope in a used book store. Macroscope was perhaps the most ambitious and sweeping (albeit scattered) sci-fi novel I had ever read. Do you think that your later work lived up to these early ambitions? Are you satisfied with your reputation as an author of light fantasy? Do you have any plans to attempt something so ambitious again?
