We do have more details about the story and gameplay, though:
Press release wrote:Phantasy Star Ø takes place on an alternate Earth 200 years after the “Great Blank,” a massive war that has reduced the once-prosperous civilization to almost nothing. The surviving Humans have worked hard to exist peacefully and have rebuilt thriving cities. Those that adventure past the outskirts of these cities, Hunters, explore the vast wilderness and hunt dangerous monsters in an effort to keep their cities safe. Players will take up the role of the Hunters and select from three types of races, classes and gender for a total of 14 customisable character types. Each character type will provide a unique experience and give players access to a great range of items, armour and weapons.
Featuring over 350 unique weapons, gamers will need to venture out to combat dangerous monsters, gain experience and meet new major characters. As players explore, they will unravel the mystery of the “Great Blank” and discover a dangerous new force that must be stopped.
