Suikoden III's character models have a perfectly suitable polygon count. When combined with the artistic style of Konami's designers and the sheer magnificence of the landscapes, one is hard-pressed to find anything wrong with the graphics. If I wanted to be critical, I might say that there were a few obvious billboarded textures in the background of some scenes, but such diagnoses are hard to make when you can't take your eyes off of the rest of the picture.
The camera-play was something to get used to, but after a few hours I was very pleased with it. As old habits die hard, you will find yourself wishing you could use that right analog or something and face the camera in a different direction, but after a while one will appreciate the picture-perfect quality of some maps as a result.
The music is another treat; more specifically, the cut scenes have excellent tracks complete with vocals in the same jap-anime style I remember from Suikoden I and II, and I was no less pleased with the sound effects.
