7th Dragon 2020 is developed by Imageepoch and was released for PSP in Japan on November 23, 2011. It is a spin-off followup to 7th Dragon. Both titles, as well as 7th Dragon 2020-II, were never localized, but the next game, 7th Dragon III Code: VFD for 3DS, is due out in the Americas on July 12. A fan translation for the original 7th Dragon was released in April 2014.
