Final Fantasy XIII-2 is a 2011 role-playing video game developed and published by Square Enix. XIII-2 is a direct sequel to the 2009 role-playing game Final Fantasy XIII and part of the Fabula Nova Crystallis subseries. Development of the game began in early 2010 and involved many of the key designers from the previous game. It includes modified features from the previous game, including fast-paced combat and a customizable "Paradigm" system. The development team wanted to improve on the gameplay of Final Fantasy XIII, while making the story's tone more mysterious and darker than the previous game. The new game's plot features heavy use of time travel, allowing players to jump between different time periods in the same location. The game was first released on the PlayStation 3 and Xbox 360, and later ported to Microsoft Windows, iOS, and Android. Final Fantasy XIII-2 received generally positive reviews from critics. The game was the fifth-best selling game of 2011 in Japan, and was followed by a sequel, Lightning Returns: Final Fantasy XIII. (Full article...)
