Judging by the lengthy opening cutscene, I could already tell that the game was going to confuse me with its terminology and lore.
The game is set in the Fabula Nova Crystallis universe that makes up all of Final Fantasy XIII, so be prepared to digest more exposition about the “l’Cie” and a handful of peculiarly-named areas like “Rubrum,” “Millitesi” and my personal favorite, “Vermillion Peristylium.”
