Lizard-alien hybrids communicate with the government directly through their interpreter, Elvis Presley, from a secret base on a crashed UFO deep beneath Denver Airport. They sold the CIA the secret of using LSD to create an army of psychic super-soldiers, and now the US intelligence agencies foment minor wars worldwide to test out the effectiveness of these troops. Meanwhile, ex-Nazis who escaped Germany after the war live in pyramids on the moon where they control the World Bank by causing tiny fluctuations in the stock market which ripple through the global economy.
All of which is super-cool fodder for the imagination. So long as you don't take conspiracy theory too seriously, it's fantastic fodder for the world of videogames. Mysterious bad guys, secrets to uncover, mysteries to solve... it's a wonder, really, that we don't see more games that use global conspiracy as their theme. Of course, the smash hit in the genre will remain Deus Ex, just as Robert Anton Wilson's terrifically weird Illuminatus remains the ultimate in conspiracy literature (whatever Dan Brown might think).
