I wonder why people automatically assume that One Piece is for kids? There's a lot of violence, and even a lot of blood, in it. The series is more for teenagers than kids, but I guess the art style makes people write it off as a kiddie cartoon.

As for the game, I think it looks kind of fun. However, if there's no Japanese voices in the game, I really do not want it. The English ones are just too bad to deal with.

Well from what I've seen of the anime it is very kiddish. I mean the main character to me just says lame joke after lame joke. Not to mention a face which makes me want to punch him. Just my opinion, I see by your avatar you think otherwise.

I heard it was a lot better before it was localized though.

Looks like OP:Ultimate Adventure.

Oh yeah One Piece is way better in Japanese. MyKidsTv Screwed the series.
