Riddle of the Sphinx: An Egyptian Adventure

Much of the history the game mentions early on, from Edgar Cayce's predictions to the habit of the Egyptian authorities to close down foreign investigations of structures just when those involved feel they are near a breakthrough are historically accurate. (The latter is most probably done for preservation of the ancient buildings, rather than any attempt to hide some deep, dark secret.)

Those interested with much of what the game entails may want to further investigate the works of such New Age 'pyramidologists'. It should be noted, however, that such is based on very limited evidence and much speculation and is therefore frowned upon by conventional investigators.

Although they couldn't be entered into MobyGames' database as such, there are some additional credits in the manual:
