Visually, Swashbucklers isn't the best looking game, though the game's style grew on me the longer I played. Though the game tends towards more "realistic" visuals, they are more inline with the realism found in the GTA series. Characters have a very distinct feel that, even though they don't exactly fit with the game's time period, still feel like they probably could. The game's most impressive feat are the massive maps, especially the expansive, open-sea sailing areas.
Although the visuals have some merit, sound isn't very good. Dialogue is spoken, though all you hear is warbling and noise. Instead, you have to read everything, including Captain Gray's conversations with himself. I don't mind reading text, though I found myself wondering why the developers bothered with the noise since it doesn't contribute anything to the experience in the long run.
Surprisingly, music is not only the best element of the game's presentation, but probably the best aspect of the entire game. There aren't a lot of songs on the soundtrack, but all are really good and add a great amount of atmosphere to the game.
