Square Enix released Dragon Quest VIII: Journey of the Cursed King and Dragon Quest IV: Chapters of the Chosen for iOS and Android in the West. The next game scheduled to come out is the Dragon Quest that started the entire series – Dragon Quest I.
"This is new information that hasn’t been pushed out much, but we are going to be releasing (in order) from Dragon Quest I, starting sometime in September, and then we’ll be releasing subsequent games like Dragon Quest II and Dragon Quest III every month, maybe every two months," said Noriyoshi Fujimoto, producer of the Dragon Quest mobile series, in an interview with Siliconera. "In terms of pricing, it’s still yet to be determined – but because these are classic games, the cost will probably be lower than Dragon Quest VIII and Dragon Quest IV which are currently out."
"In Japan, the classic games have gotten a revamp in terms of quality, so we’re going to take one of the newest iterations of the classic Dragon Quest I and relocalize it for the mobile version. You may be aware, but the first Dragon Quest released in North America (note: this was released as Dragon Warrior) was released in 1989 – so we’re not going to take that version, we’re going to take a revamped version."
Siliconera will have more about the Dragon Quest series from Fujimoto and Dragon Quest series producer Yuu Miyake soon.
