FFXV´s story centers around Noctis Lucis Caelum, Crown Prince and protector of Lucis, the last remaining kingdom in the world with control over crystals. The game's focus is to examine the characters' humanity and distinguish it from the fantasy setting in other titles in the series. The story focuses on friendship, destiny and legacy.
Two demos have been released for the game: The Duscae Demo and the Platinum Demo. The first one is an early demo created from a slice of the Final Fantasy 15 world. It contains a sizeable chunk of content, including two boss battles and a summon, as well as an introduction to the main characters. The Platinum Demo is a shorter, more defined demo designed to show off the concepts and technology from Final Fantasy 15.
On late March 2016, during a NicoNico streaming, it was confirmed that the game would take about 50 hours to complete the main story.
