One of the producers mentioned the possibility of a single-player version of Dragon Quest X that could be released for the international market.
The vast majority of the numbered Dragon Quest games are now available across multiple platforms, with the early titles being readily available on mobile phones, high-quality ports of Dragon Quest VII and VIII existing on the Nintendo 3DS, Dragon Quest IX being a DS title (and therefore playable on a 3DS), and Dragon Quest XI recently being released on the PlayStation 4.
The one missing numbered Dragon Quest game is the tenth one, as it was an MMO that was released across multiple different systems in Japan.
The competitiveness of the MMO market, coupled with the less than welcoming reception to the Dragon Quest series in the West has meant that Dragon Quest X didn't see a full release outside of Japan.
There is still hope for an international release of Dragon Quest X, but it would be in a drastically different form.
Yu Miyake (one of the producers of the Dragon Quest series) mentioned the possibility of a single-player version of Dragon Quest X that could be released for the international market, as well as being available in Japan.
Miyake stated that Dragon Quest X has a lot of rich stories and that he would like to share them with players, including the ones overseas.
The reason why there is an interest in making a solo version of Dragon Quest X may have something to do with the game's reception in Japan. Dragon Quest X is one of the worst-selling games in the series, even though Dragon Quest is a huge franchise in Japan.
The number of sales and subscriptions for Dragon Quest X is also a fraction of what Final Fantasy XIV has accomplished, which is another MMO made by Square Enix that had a much rockier start and still managed to snag a wider audience.
Yu Miyake stated that the portable Dragon Quest games didn't sell well overseas, which is partly why the series shifted from Nintendo systems to the PC and PlayStation 4, which have a much wider user-base.
Dragon Quest XI: Echoes of an Elusive Age is a strong contender for Game of the Year, yet it didn't sell as well as other titles that were released during the same period (most notably Spider-Man). Is it even possible for the Dragon Quest series to finally find a huge audience in the West that it so strongly deserves?
Only time will tell, but the fact that there is a conversation about an international version of Dragon Quest X gives us some hope for the future of the series.
