Final Fantasy Type-0
"Final Fantasy Type-0" was originally titled "Final Fantasy Agito XIII", envisioned as a game for mobile devices. It was conceived in 2005 as part of "Fabula Nova Crystallis Final Fantasy", a subseries of "Final Fantasy" games linked by a common mythos. "Agito XIII" was the final original "Fabula Nova Crystallis" game to be created. The decision to make it a mobile game was based on the popularity of "". Hajime Tabata, who contributed to the "Fabula Nova Crystallis" mythos, was searching for a new project after finishing "Before Crisis" and became the game's director. "Before Crisis" producer Kosei Ito acted as producer before his move to Capcom prior to 2009. Beginning development in 2006, it was first announced at that year's Electronic Entertainment Expo (E3). It was said to offer on-the-go access to the "Fabula Nova Crystallis" universe, using gameplay functions exclusive to mobile phones of the time. The concept was to deliver a game for mobile platforms equivalent to a console game from the main "Final Fantasy" series, and to make it available in its entirety upon release rather than in episodic format.
X-COM
Because of the series' popularity, various other developers have created spiritual successor games similar in theme and tone of the "X-COM" games (sometimes called ""X-COM" clones"; Julian Gollop also himself called turn-based tactical game genre in general as "sons of "Rebelstar"" in a reference to one of his earlier games). The level to which they borrow from the original series varies.The franchise was also referenced in the "Civilization" series of strategy video games that had partially inspired "X-COM" in first place. The original game received an unofficial sequel in the 1997 expansion set "Civ II: Fantastic Worlds" for MicroProse's "Civilization II", in a scenario set on the Phobos moon of Mars. Firaxis' "Civilization V" features a unit type named XCOM Squad.
