This book was the fourteenth in the Tor Double series, in which two novellas were printed back-to-back and in opposite orientation to one another with separate covers, in the tradition of the Ace books double format they started in the 1950's. The Saturn Game has a lovely NASA photograph of Saturn as its cover. The story first appeared in the February, 1981 issue of Analog magazine and it won both the Nebula Award and the Hugo Award for best novella of the year. (I didn't vote for it; my favorite that year was True Names by Vernor Vinge.) I never much cared for The Saturn Game; it concerns a group of scientists who get involved with a fantasy role-playing game while on their way to Saturn and the growing effect it has on them as time passes. Though this was long before RPGs and cosplay was a big thing, Anderson drew heavily on his own experiences as an early bigwig in The Society of Creative Anachronism as Bela of Eastmarch (who's named in the story, in fact) in writing The Saturn Game. I didn't think the story presented a fair picture of the concept, and thought it contradicted itself frequently. Was it good or bad, did it do harm or good, should they have banned the game or embraced it? It just didn't work for me as it was written, but obviously most other readers liked it a lot. The other novella, Iceborn by Gregory Benford and Paul A. Carter, was quite good. It's a little dated now from a political standpoint, but I enjoyed it very much. It covers a whole lot of ground; the exploration of Pluto, contact with two sentient and very alien races, the philosophy of space flight, the nature of religion, the spirit of exploration... I kept turning pages and wanted more. It's an excellent and thought-provoking story in the grand hard science tradition.
