Wanted: Dead or Alive. Live for fun, live for the adventure.
Half the game of One Piece is survival. It requires [you] to keep food charts and survive the harsh seas and the incredibly dangerous waters of the Grand Line. You have a choice in the game: do you become Pirates, Bounty Hunters, or Marines? [Your decision will determine] who you fight for and against in the great world of the sea.
The One Piece game uses several standard "D20" concepts in a blend with homegrown rules intended to support the setting.
