Just finished 'The Moon Maze Game', as mentioned earlier. Can recommend, kind of 'Dream Park: Die Hard On The Moon', but a lot of fun.
@Miss Chicken: if you haven't read the Dream Park novels, they're pretty good. It's a theme park where people/actors go in to play games that are recorded and put out as movies, sort of imagine any action movie played by actors making it up as they go along, cross Indiana Jones with Survivor. The actors compete for points and international standing, and the game can then be played at home by people who buy it, which has a whole bunch of different endings built into it, like any game. The places the games are played in domes that have all manner of projection equipment, and sets, and Non Playing Characters. And the games themselves are unusual in themselves (Cargo Cult mythology, the Inuit version of Fimbulwinter, Californian Voodoo, and HG Wells's Form The Earth to the Moon... on the Moon).
