4 out of 5 rating for Skull & Shackles Adventure Path
This is the pirate AP. It delivers buried treasure, sea battles, and amoral shenanigans. Parts of it are too sandbox-y and its easy for PCs to lose sight of what story there is (somewhere in book 2 or 3), but with a firm GM hand this AP will pay out everything the players expect from it.
5 out of 5 rating for Skull & Shackles Adventure Path
This is the most fun pirate game for D&D (and D&D derived) rules I ever played. It gives you the feeling of swashbuckling adventure from the Pirates of the Caribbean movies and always makes sure to have the party interested in engaged in the game world.
