Assassin's Creed 4: Black Flag tells the tale of redemption amid a era filled with licentiousness, according to scriptwriter Darby McDevitt, which should shed some light on the wenchery we saw in the announcement trailer.
According to ans interview with McDevitt on Polygon, in the game, Edward Kenway and his wife have issues because of his penchant for a little ménage now and then, plus he's a true pirate in the sense that he tends to be a "raucous and bawdy chap."
However, despite all his flaws, he's set out upon the high seas in order to become rich, and thus redeem himself in the eyes of his family and society. He better not catch syplllis then. That might piss the ole wifey off a bit.
"His primary motivation in Assassin's Creed 4: Black Flag is to get rich and prove himself a ‘man of quality' to his family and betters," said McDevitt. "So there is a special woman in Edward's life, but there are also other not-so-special women as well."
Some of theses "not-so-special" women will come in handy for the pirate, because as an NPC, they can be directed to distract targets using the timeless art of seduction.
"While this scene in the reveal trailer was clearly designed hint at the pirate lifestyle, there is a gameplay element here, to show that you can use certain NPC characters to more effectively achieve your goals," said McDevitt. "You might have noticed that the woman [who was part of the earlier ménage] in the foreground seduced his target at the end of the trailer."
As will all games in the series, everything is scripted - no choices in who you form bonds with - but it will still be more "open and free than ever before," and Kenway will even run across famous pirates such as Anne Bonny.
Assassin's Creed 4: Black Flag is out on October on PC, PS3, Wii U, and Xbox 360.
