Final Fantasy Type-0
While working on "Final Fantasy XV", Tabata decided to make a high-definition remaster of "Type-0" for eighth-generation consoles. Developed by Square Enix and HexaDrive, "Final Fantasy Type-0 HD" was originally announced at E3 2014, and released worldwide in March 2015. After "Type-0"s release, Tabata stated in an interview that he wished to explore the distant history of Orience after the events of the game. Trademarks for "Type-1", "Type-2" and "Type-3" were registered shortly after the "Type-0" trademark, but it was suggested that they were simply a protective measure. During interviews given in 2014, Tabata commented that he wished to work on "Type-1" after completing "XV", and later explained the conceptual "Type" series as a means of publishing "Final Fantasy" games too experimental for the main series. He hoped to continue with the "Type" series if "Type-0 HD" was commercially successful.
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.
