Assassin's Creed: Black Flag, anything like it?

So I'm playing Black Flag and really rather like it.The piracy element is tons of fun, I love sailing the ocean taking down ships, discovering new locations, seizing forts, etc. The problem is, I generally hate the 'Assassins Creed' element of the game. 'Tail' missions are excruciatingly dull and frustrating, for example... and are typically completely inane as well. Every time my high-seas shenanigans is interrupted for some 'do it this way and only this way' ground mission, I like the game a little less.

Is there a game, either out now or in the works, that plays in a similar style to Black Flag, but that focuses on piracy? Lets me bargain with enemy ships/forts, start up a fleet of captured ships and choose which one I want to sail? Marry a governor's daughter and start up a family?

Oldschool expansive pirate experience stuff as from those awesome old DOS games with Black Flag's modern graphics, play-style and combat mechanics would be fantastic.
