In The Secret World from Funcom players chose one of three factions to ally themselves with. Part of the basis of the story of this MMO is that these three factions are secret societies that have been battling each other for years through conspiracy theories, boardrooms and in the field.
The factions are: The Dragons, who instigate chaos and want violence. The Templar, you know, the whole battle evil thing. The Illuminati, who want wealth and power.
The Secret World will be in stores in April 2012 for PC and Xbox 360.
