After friends have recommended but the game, I slammed.
In short:
The changes make sense of the new features, such as hunting, Schifskämpfe are raised, I just do not understand why the game starts so lame.
Who the initial stage by holding might think here has only a new story on old gameplay set, after the first "chapter" you get to know the new features.
Until then brings a story and features from not, one has but survived, the jump is as large as the time of AC1 to AC2.
It is definitely worth it.
