Re: a real Pirate Adventure

I'm extremely obsessed with all of the fantasy / adventure like add-ons / expansion packs and thought perhaps a pirate expansion pack could be fun or interesting! Life on the sea, Ship designing, crew building, treasure hunting, pillaging (If you're into that kind of mischief), pirate battles against other pirates / law. Swords, guns, cannons, the whole nine yards. 

Does a pack like this already exist? ... If not, could it have potential?
