The first installment of the series was released in Japan on December 18, 1987. Subsequent games are numbered and given a story unrelated to previous games, so the numbers refer to volumes rather than to sequels. Many Final Fantasy games have been localized for markets in North America, Europe, and Australia on numerous video game consoles, personal computers (PC), and mobile phones. Future installments will appear on seventh and eighth generation consoles. As of November 2016, the series includes the main installments from Final Fantasy to Final Fantasy XV, as well as direct sequels and spin-offs, both released and confirmed as being in development. Most of the older games have been remade or re-released on multiple platforms.
