G'day!
I have been very interested in several discussions of what SF influenced the OTU. I think it must have been very important that I never read any EC Tubb.
After the last such discussion I began to think about some of the things that I have read that have made my SF RPG setting different from the OTU. Not all of it has been fiction at all: C. Northcote Parkinson's The History of Political Thought and James Frazer's The Golden Bough were major sources, for instance, as were various bits of ancient and mediaeval history. And I also borrowed some things from non-SF fiction, such as the TV show Edge of Darkness. The major SF influences on my GMing were as follows:
Isaac Asimov: Caves of Steel, The Naked Sun
Lloyd Biggle, Jnr: Monument
