Quotes from Lewis Carrol's "Alice in Wonderland" appear periodically throughout Far Cry 3, with the first, pictured to the right, appearing at the beginning of the game after the player is rescued from Vaas and his pirates by Dennis.
Other quotes appear after the player has completed significant events in the story.
Parallels With Assassin's Creed
Assassin's Creed 3 also begins with the same quote pictured to the right.
But that isn't the only parallel between AC3 and FC3.
During the first Lost Expeditions mission, players almost immediately run across a folder with Abstergo's logo on it, implying that Far Cry 3 and the Assassin's Creed games actually take place in the same universe.
Over the course of the rest of the mission and further Lost Expeditions missions, other clues indicate that yes, Far Cry 3 is happening across the world at the same time as Assassin's Creed 3.
