Via Famitsu we learn that the Square RPG campaign Lightning Returns: Final Fantasy XIII will last 20 to 30 hours dale, but if we want to see all of the game without skipping any secondary mission or any event, the title can get to 50 hours to complete. In addition, after finishing for the first time the main campaign, you will be able to play again by changing the level of difficulty. Our alter ego at that point will have different customs and quirks and abilities increase.
