Gorram NDA. I'm afraid Cthulhu will eat my goldfish if I talk.
The inspiration for the game is pretty clearly from
The Illuminati Trilogy, which was also written under the supposition that every conspiracy theory was actually true. Secret World has its own ideas, though, so don't expect to run into the John Dillinger Died For You society or overcome evil rock bands by via mass orgies with ancient Greek goddesses.
(Well… maybe the latter. They haven't said much about the end game yet.)
P.S. Also, best use of a zipper in a trailer:
