OH that would be so sick.
they could add in environmental stuff, like waves that go over and knock ppl off the boat if you were too slow to move from that portion..
collecting treasure and bringing it back to your ship..
accidentally aggroing a parrot / monkey somewhere in the midst of the aoe lol.
i wonder if they could implement a system for the whole team to help customize the ship's sails before the game starts. it would be utter chaos.
