For the most part Duels remain unchanged from previous titles. The game still has three battle modes of Dungeon Crawling, Duels, and War Battles. Several new mechanics were introduced and some series standbys were altered to compliment the new additions. Suikoden III was a radical departure from the earlier entries in terms of gameplay mechanics.
It is the first Suikoden that is released in full 3D. It is the final game the series creator Yoshitaka Murayama worked on. It was released in 2002, with a manga version published in 2004.
