This series has made nice progress over the years. Every new game incorporates new elements, but retains the things that fans liked from previous games. Fans of the
Legend of Heroes games like old-school, 2D graphics. One thing I still enjoy is how the characters are shown during dialogue segments. Instead of just a box showing what the character is saying you see a large, animated bust of the character. Depending on how the mood is at the time, you'll see a slightly different expression on each character.
Legend of Heroes III: Song of the Ocean has a collection activity that revolves around a photo book with all the different expression each character shows during the game. Lightweight fun... There are pets in the game that have persisted through the series and this time, you play through with a dog character. The dog, Jan, is more than window dressing since he is one of the first characters with the ability to do healing magic.
Each new installment in this series looks better and Song of the Ocean is no exception. The lighting as you explore the world and in the dungeons is more like what you expect to see in a 3D game. There are textures everywhere and motion in both the landscape items (clouds, water, etc.) and the character models (hair blowing in the wind or as you run) that make exploring really pleasant. The characters in the game are traveling musicians, so you can bet the musical themes are well done. There are lots of little music segments that you prompt by stepping up on stage in towns; many times these moments are central to progressing in the game.
