Final Fantasy Versus XIII is an action role-playing game developed by Square Enix as part of the Fabula Nova Crystallis subseries of the Final Fantasy franchise. Initially announced in 2006, it was intended to be a companion title to Final Fantasy XIII, featuring a darker narrative and a more mature tone. The game follows the story of Noctis Lucis Caelum, the prince of Lucis, as he embarks on a quest to reclaim his homeland from the invading Niflheim empire. After years of development challenges, the project was rebranded as Final Fantasy XV and released in 2016. The game retained many elements from the original concept, including its focus on friendship and the bond between characters. Final Fantasy XV received positive reviews for its open-world gameplay and engaging story, marking a significant evolution in the Final Fantasy series.
