According to a recent article on Kotaku the popular Dragon Quest franchise could be bringing the latest MMO, Dragon Quest X, to the Western audience. The game was released to the Eastern audience and was met with a hugely positive response. Fans have already created petitions to get the game over to the Western seas but Square Enix are a little unsure on exactly how they plan to do it.
Miyake: Of course we are. However, with the overseas market, in regards to a "Dragon Quest-ish" management, standards and methods of play vary from country to country, so I don't think we'll be able to use the single game worldwide method like with Final Fantasy XI.
Saitou: This is just my take on it, but it appears that different countries play games at different speeds, and the community management is also diverse. It's more than just if players would be able to enjoy universal seasonal events, so I believe we should manage countries and areas separately. That's why I think we should have separate servers for each country.
I think the biggest change needed would be that of the subscription model. Currently players can experience a few hours of player per day, but they'll have to subscribe to lift that restriction. That's not really something that would work with the Western audience so it will be exciting to see if they can bring something a little more unique.
