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.
Final Fantasy Tactics
The world of "Final Fantasy Tactics" has been featured in several other Square video games. After the game's release, the development staff went on to develop "Vagrant Story", which featured several subtle references to "Final Fantasy Tactics". In an interview with the French video game magazine "Joypad", Matsuno stated that both titles are set in the same fictional world of Ivalice. During the development of "Vagrant Story", Matsuno and Sakaguchi initiated a sequel to "Tactics", which would have used 2D graphics due to issues with 3D development at the time. Due to the team's committent to "Vagrant Story", the project was outsourced to an unspecified developer, but was cancelled for unspecified reasons.
