The game began development in 2011. Revealed during a special festival in December 2013, it was designed as the 20th anniversary title for the Tales series, returning to the series thematic roots as established in Tales of Phantasia and featuring a revamped battle system and open-world design. It features multiple staff members from previous entries in the series: they include producer Hideo Baba, battle programmer Tatsuro Udo, designers Kōsuke Fujishima and Mutsumi Inomata, and composers Motoi Sakuraba and Go Shiina. It has received positive reviews in Japanese gaming magazines, and sold over 400,000 units in its first week. Despite the praise, it has received criticism from fans for its handling of the games characters.
