Graphically, the designers for Tradewinds Odyssey did an awesome job with the people, the colors, the ships, the detail - everything there is about this part of the series. They make the game look like the pottery and paintings from ancient Greece, which is great to add atmosphere to the game itself. The details are awesome, even when you are out sailing the waters or fighting ships. And, the characters that you'll meet are also extremely well designed, with the clothing, hairstyles, and general feel of ancient Greece. The one thing I did notice about the characters is that they do tend to look alike after awhile, but the game is just so good in every other aspect that you don't really mind.
You can see from the screenshots below the beautiful art work, the wonderful colors and just get a general feel for the game. (I have to admit that I loved playing the Minotaur... the people in town will make fun of you, crack jokes, and everything else, which is a great aspect to the game as well.)
