I think that's the game where you play as a Pirate? I can't remember for sure. I think I've tried that game after the Eclipse War CBT period.
not just a pirate... you can get treasures and hunt discoveries as adventurers or do nanban trades with east asia for traders, also traders can make cannons/make booster cloth/cooking/making investment book
head up to ogp Uncharted waters online
and please if you saw LordZiad/LordDiaz in game block, he is troll to the game
