I quite like the feel of Harry Harrison's novels, his most famous of which are very much the 'one man against the universe' types of affairs. Invariably in Harrison's books, the central character is usually intelligent, witty and fair minded, with a strong sense of self-preservation and occasional criminal tendencies, whereby they often have to bend the rules to either right a particular wrong or simply to get on in life. Which is very Elite-like.
Harrison's books tend to walk a very fine line between action, adventure, parody and satire, giving them wide appeal. He often satirised other sci-fi works, notably pro-military novels such Heinlein's Starship Troopers (which is actually a very good book itself) with his Bill the Galactic Hero series, largely because Harrison was very anti-military himself after having served in the US Army in WW2. But it is with his Stainless Steel Rat series of novels where Harrison's writing really shines, and these books are an almost perfect recipe for the Elite premise of one player trying to get along in the future, but not taking things in a too po-faced or serious manner.
Harrison could certainly write very serious sci-fi when he wanted to though, notably with Make Room! Make Room!, which became the basis for the 1973 movie Solyent Green, although much of the subtle homage to writers such as Hammet and Chandler which one finds in the novel is gone from the film adaptation.
Ultimately, it is his grounding in very human traits and issues, set in a sci-fi backdrop which makes his books such a worthwhile read in my opinion. The sci-fi elements tend to be there to add colour and scope to the tales, rather than to provide a convenient deus ex machina for the storyline, which is something a lot of sci-fi is often guilty of, notably Star Trek with its 'what if we reverse the cross-flow polarity of the dilithium crystals in Jeffries Tube number six?' b*llsh*t solutions to supposedly insurmountable plot issues.
Of course the really great thing about all that is, one hardly needs to actually include elements of Harrison's writing in Elite to emulate it, since it is more of an attitude one can adopt for one's character when creating one's own story. I suspect there will be quite a few players out there emulating Slippery Jim DiGriz.
