At first I was really skeptical because the pirates scenario. Actually, my genre, but is not at all far from it. The game is just awesome. - The menu navigation is something fresh, but easily seen through and even beautiful. - The graphics are as usual at AC parts, beautiful and just the Caribbean flare makes right mood for a holiday. ;) - The sound know here and there, although inconsistencies, but there can be overlooked. If then when he killed his last opponent with the final hit even while struggling. Maybe that's also just me, have there no comparison. - The gameplay itself is not changed here as well to the old parts large. Familiar climbing, fighting, stealth and gathering. Said Ubisoft has also always good job and therefore it does not need any change. - The story is very interesting, Spain against England well done against pirates and of course Assassin against the Templars, which is combined and is really fun. The size of the map is huge, only you have to say, the lack of major cities, what can be overlooked, as it is most of the time at sea anyway, unfortunately. About driving on the lake, however, I will write nothing that would gespoilert too much, also have to get the experience for yourself. ;) For the story outside the Animus, you have to get used to, but also because Ubisoft has done a lot right.
In conclusion: Assassin's Creed IV Black Flag is, for me personally, in addition to the first and second part of the best AC in the market. For fans a "Must Have" but also for newcomers as "first part" playable.
