The reason Japan has it a month before us is the Japanese are the one who make .hack games. since the make it we must have people make it into english instead of Japanese and if you ever have a anime on dvd and you turn the Japanese on the boices sound very diffrent. So im guessing that they have to get people to talk for the game. I might be wrong and if i am some one plz correct me but thats why i belive we get the games later.
