Uncharted Waters Online is set within several timelines during the Age of Exploration as a romantic and historic fictional account of the era. Inconsistencies are found in the presence of Christopher Columbus and Elizabeth I of England as well as in some quests. However despite some of these timeline inaccuracies the game offers educational content in the form of exploration of geography and culture. Players can discover quests with historical value such as learning about the economic decline of Venice, or the rise of England as a naval power.
As an online game it offers Player vs Player combat areas and factional warfare as well as socialization in the form of in-game chat and card games.
