Dragon Quest X is going in a much different direction than most of its predecessors. While DQIX did incorporate multiplayer elements, DQX is going even further in the direction of being an MMO. The Wii (and Wii U) game is without a release date as of yet, but a beta is planned to iron out any kinks before Square Enix unleashes the game (complete with subscription fees) in Japan.
A Japanese website filled with information on the beta has just been launched. Gamers can begin applying for access beginning sometime in mid-November, although you must live in Japan and have a free Square Enix Members account to be considered. You’ll also need a Wii that can connect to the Internet and be willing to actively participate by submitting bug reports and things of that nature.
