What is the title of the flagship game that was designed to be the flagship title for the series, per the paragraphs which follow?

Fabula Nova Crystallis Final Fantasy[c][d] is a series of games within the Final Fantasy video game franchise. It was primarily developed by series creator and developer Square Enix, which also acted as publisher for all titles. While featuring various worlds and different characters, each Fabula Nova Crystallis game is ultimately based on and expands upon a common mythos focusing on important crystals tied to deities. The level of connection to the mythos varies between each title, with each development team given the freedom to adapt the mythos to fit the context of a game's story.

The series, originally announced in 2006 as Fabula Nova Crystallis Final Fantasy XIII, consists of seven games across multiple platforms. Final Fantasy XIII, designed as the series' flagship title, was released in 2009. The creative forces behind the series include many developers from previous Final Fantasy titles, including Shinji Hashimoto and Motomu Toriyama. The mythos was conceived and written by Kazushige Nojima. The first games announced for the series were Final Fantasy XIII, Final Fantasy XV (as Versus XIII), and Final Fantasy Type-0 (as Agito XIII). All three games went through delays. After Final Fantasy XIII and Type-0's releases, their respective teams used ideas and concepts from development to create additional games. For later games, other studios have been brought in to help with aspects of development. Final Fantasy XV was distanced from the series brand for marketing purposes, though it retains thematic connections.

Seven titles, the original three projects and four sequels or spin-offs, have been released as of 2016. The series is complemented by works in related media, including companion books, novelizations, and manga. Final Fantasy XV notably expanded into a multimedia project, spawning a feature film and an original animated webseries. Individual games have generally received a positive reception, although opinions have been more mixed over various aspects of the three Final Fantasy XIII games. Reception of the mythos' use in the released games has also been mixed: while some critics called it confusing or too similar to the lore of the main series, others were impressed by its scope and use. Retrospective opinions on the series have also been mixed.
