I'm very happy with it. The only mayor bugs I ran into are that you can fall off a boat when running. But other than that everything I saw worked. But I couldn't play all the missions because of my graphicscard. But a new one is on it's way and than just hoping that the patch fixes everything.
The one thing that does enoy me is that when you are behind the wheel and you use the actual control's of the ship not the ones in the leftcorner, the fog goes away. When you are in a foggy mission and use the controls you just see clear sky. But I thought this was going to be fixed in the patch to.
So all in all for what I have seen a good game!
