Also seen graphically the game is absolutely top notch! The characters are so properly implemented in 3D, as one could wish and convince with their new outfits they least like their 2D models in the anime. What a big plus is that the original voice actors from Japan were maintained and all speech parts are synchronized.
The combat system is on eating firm also after a few minutes and the fact that you have to unlock new techniques only increases the fun - especially because you have to unlock for each character separately, has pronounced to fight with anyone if you have a reasonably uniform would have strong team (of course it is not to deny that Zorro, Luffy and Sanji the others are a little ahead).
The Level, and islands with their various opponents are quite different and varied, since they partly offer new opportunities to bring new items or are significantly ford Ender.
The only drawback in my opinion is the storage system that works only handled manually, when you return to the ship. Say, if you go Game Over, you have to start again at the ship to the point at which you last saved. This is especially annoying if you end up a dungeon (because those are the islands) with a lot of effort encounters a boss, has no desire to run back the whole long way and then scrapes ... but that's still quite acceptable.
A great action adventure (RPG) with a great story, a lot of humor (thanks Brook) and a lot of fun, not only for One Piece fans.
