Mobius Final Fantasy

Mobius Final Fantasy is a role-playing game designed for mobile phones. The players could control the game's protagonist Warrior of Light (Wol) while navigating Palamecia. Players could customize settings, graphical quality, and adjust controls for their dominant hand. During local navigation on the field map, the players had to tap a location on a map for the character to travel.

In some self-contained areas, the players could directly control the character. Along with standard navigation, the players could navigate the game world using a fast-travel system, progressively unlocked as they progressed through the story. Many of the features in the game, such as the leveling system and exploration, were similar to those from previous home console Final Fantasy games.

Wol, the main protagonist, awakes stricken with amnesia in the foreign world of Palamecia. He is one of multiple "Blanks", people brought to Palamecia from other worlds and suffering from amnesia. Palamecia is under attack from the armies of "Chaos", and Wol must fulfill a prophecy in Palamecia that one of the Blanks is a "Warrior of Light" who will free the world from its darkness. Wol is aided on his journey by Princess Sarah Lotte Cornelia, the princess of a kingdom of Palamecia, and Mog, a moogle who volunteers to help in Wol's quest.

Chapter 2, entitled "Prediction and Hope", includes Wol and Mog adventuring through the Ishtar desert and Rune Temple. A side quest was also included, entitled "El Dorado of the Oblivion", which is set in the ruins of "Gold Volost of El Dorado".

The concept behind Mobius was for a mobile experience comparable with console games and "a rich gaming experience, anytime, anywhere". Though it was possible to make a smartphone game equivalent to console games, it had yet to be done, so game producer Yoshinori Kitase sought to fill this perceived gap in the market. It was called the first Final Fantasy mobile game of this scale. While creation of some artwork and graphics was outsourced, most of the concept work and development was done in-house by Square Enix's Business Division 1.

Instead of a new development team dedicated to mobiles, the production team was largely made up of veterans from the console Final Fantasy titles. The staff included scenario supervisor Kazushige Nojima and producer Yoshinori Kitase. The story is connected to the original Final Fantasy only thematically through its focus on "warriors of light" fighting against chaos and darkness: it is not a remake or directly related to the plot of the original. It is also considered by the team behind the game as a full entry in the series rather than a spin-off.

During its pre-registration period, the game received 200,000 registered users. By July 12, just over a week after release, the game had one million registered players in Japan. This number had expanded to over two million by the following month. Speaking after release, Kitase said that Square Enix considered the game a success as it introduced the mobile community to AAA-style graphics.

In Square Enix's 2015 annual report, Mobius was noted as one of their successful mobile titles for the year, stating that the higher production values when compared to other mobile games on the market had contributed to its popularity. In addition, Mobius was among the finalists for the 2015 Unity Awards for mobile games in the "Best 3D Visual Experience" category, and was named among Japan's "iTune's Best of 2015" by Apple Inc.
