Everyone you know from One Piece is in Chibi form in this game. You choose one of the 6 crew members of the Straw Hat Pirates. You choose a board containing territory squares. You must try to take over as many as possible in order to win the game. With over 9 different board styles and several games. One Piece Pirates Carnival is playable for 4 people to play.
The thing the ruins this game is 4Kid's control on the dialog and features of the game. What you see for the English speaking version of this game isn't uncut. 4Kids took out a great deal of characters that weren't introduced in the anime. While only leaving 5 characters who weren't dub in the anime yet.
Since it's edited, the games with the newer characters were replaced with someone we already have seen before. While most of the games received alterations to match the replaced character's personality. With the use of voice acting from the 4Kids One Piece included in the game. Makes it all a disappointment to the fans who hated the way 4Kids did the series.
If it weren't for the heavy alterations and editing. As well as the bad voice acting, this game would of felt more complete and intact. But not sure if it'll ever be re-done by Funimation.
You also get to hear the 4kids voices of Eneru, Wiper(Wyler in the game), Bellamy, Satori, and Blackbeard. Which are characters that never been dubbed in the 4Kids series. This is one of the fewest 4Kids One Piece games to give you an idea on how terrible it would of been if they did dub the Skypiea Episodes.
In conclusion, it's not a must buy if you're a 4Kids hater or hate "Too Easy to Win" video games.
