One of the best Wii U games to date!

The game leaves a lot of freedom ... once you get has its own boat you can with a few exceptions (at the beginning may not be quite free rumfahren) basically do whatever you want ... follow the story, ships capers ( but beware, it is shot back ... not the same as having the greatest invest :)), islands to explore (treasures, find secrets and Co.), whales and sharks hunt ....
There are also many successes that you incidentally still can make master (and there are some).

Once the main mission accomplished and the credits is over (which you should look at in any case, since one learns something about the future) you can then continue to explore the seas to find not yet explored islands, challenges and Co. or to cope and last but not least, there are also the options menu, a progress bar where you see exactly where there's what to do ... seis now one of the last missions in which you have not obtained all the bonus objectives ... in almost every mission the main story, there are min. to achieve two additional objectives and there also can be then already asked and instructions on how to perform certain actions (which can be read in the options ... knew until just now is not how to disarm an enemy :) ).
