Lost Odyssey is a turn-based Japanese role-playing game designed by Hironobu Sakaguchi, with dream segments written by novelist Kiyoshi Shigematsu. The player controls the immortal Kaim who has already lived for thousand years but lost his memory. He must explore world with his friends to remember everything and find who is behind his amnesia. The game features a lot of locations to explore, characters to talk to and various items to examine and use. As the player progresses through the game, the story unfolds through numerous cut-scenes.
The gameplay of Lost Odyssey is quite different from modern JRPGs. It uses traditional mechanics such as random encounters and battles that take place in separate locations. The combat system and character development are based on skill learning - mortal characters can only learn class-based skills from leveling up, while immortal characters can learn any skill from items and must equip them in special slots. The game was released on the Xbox 360 console.
