Final Fantasy XV is an action role-playing game developed and published by Square Enix as part of the long-running Final Fantasy series. It was released for the PlayStation 4 and Xbox One in 2016, and for Microsoft Windows in 2018, with a version for Google Stadia scheduled for a later date. The game features an open world environment and action-based battle system, incorporating quick-switching weapons, elemental magic, and other features such as vehicle travel and camping. The base campaign was later expanded with downloadable content (DLC), adding further gameplay options such as additional playable characters and multiplayer.
Final Fantasy XV takes place on the fictional world of Eos; aside from the capital of Lucis, all the world is dominated by the empire of Niflheim, who seek control of the magical Crystal protected by Lucis's royal family. On the eve of peace negotiations, Niflheim attacks the capital and steals the Crystal. Noctis Lucis Caelum, heir to the Lucian throne, goes on a quest to rescue the Crystal and defeat Niflheim. He later learns his full role as the "True King", destined to use the Crystal's powers to save Eos from eternal darkness. The game shares a thematic connection with Fabula Nova Crystallis Final Fantasy, a subseries of games linked by a common mythos which includes Final Fantasy XIII and Final Fantasy Type-0.
The game's development began in 2006 as a PlayStation 3 spin-off titled Final Fantasy Versus XIII. Tetsuya Nomura served as the original director and character designer. After a development period of six years, it was changed to the next mainline title in the series in 2012; Nomura was replaced as director by Hajime Tabata, and the game shifted to eighth generation platforms. Due to the changes, the story needed to be rewritten and some scenes and characters were repurposed or removed. The setting of Final Fantasy XV was "a fantasy based on reality", with locations and creatures based on elements from the real world.
To supplement the game, Square Enix created a multimedia project called the "Final Fantasy XV Universe", which includes a few spin-off games, as well as an anime series and feature film. Gameplay and story-based DLC is also set for release up until early 2019. Upon release, Final Fantasy XV was well received by journalists. Praise was given for its gameplay, visuals, and emotional weight, while reception towards its story and presentation was mixed. By November 2018, the game had sold over 8.4 million copies worldwide.
