One Piece: Kaizoku Musou expected nothing less from one piece
the game play is just like Dynasty Warriors 7 and the story line is the same as the anime,
chapter 1 starts in Shabondi Shotō Luffy vs the Pacifist
starting from chapter 2 Luffy Zoro and Nami explains to the last members of the crew [Franky and Brook] how everyone joined the crew starting from Nami,
I don't now if the game is going to have a different story line in the late chapters because I'm now in Water 7 chapter,
The game of course is Japanese with a Japanese menu and everything is written in Japanese but everyone is going to enjoy the game if they understand a little Japanese and I'm not talking about reading or writing I'm talking about understanding what the characters is saying if you understand that then you will enjoy the game for sure,
All in All any true one piece fan should get the game.
