The average player will complete Lightning Returns: Final Fantasy XIII in around 20 to 30 hours. If you want to see everything in the game and not skip any events, the game will take roughly 50 hours, says Famitsu magazine.
After you finish Lightning Returns: Final Fantasy XIII you can play through the game again and change the difficulty level. Your garb (costumes with different skills), abilities, and leveling up progress carry over in a second run similar to a New Game+ mode.
Lightning Returns: Final Fantasy XIII comes out on November 21 in Japan. Square Enix will release the game in the West on February 11 in North America and February 14 in Europe.
