Your journey begins as Kaim Argonar, a 1000-year-old immortal, survives the impact of a meteor crashing onto a battlefield. From this spectacular intro, you're thrust into a world on the verge of all-out war. The political intrigue of city-states caught in a staring contest is just a sideshow for Lost Odyssey's true conflict. Kaim has lost his memories, the past 1000 years mysteriously stripped from him. Kaim is not the only immortal wandering the Earth searching for his past. In fact, three other immortals have also forgotten the events of the last millennium. Unlocking these memories proves the key to thwarting a sinister plot that threatens two worlds.
It's a promising premise that's never fully realized. The main plot quickly becomes clichéd, convoluted, and (in the end) silly. The story's villain is revealed to be a power-mad tyrant straight from central casting. Most people play RPGs for the story and Lost Odyssey's primary storyline is average in its best moments. But intertwined with the main plot are several smaller stories that are intriguing, engaging, and adult. No, not "bare-assed blue aliens" adult, but mature nonetheless.
Kaim is our first beleaguered soul. In the first few hours of Lost Odyssey, he is portrayed as a quiet loner, with little persona. But around six or seven hours in to Lost Odyssey, we get our first significant revelation about Kaim and suddenly the character opens up and we learn the pains of being immortal. Though Kaim must reclaim his memories to save the world, he would prefer they never be recovered. A thousand years brings a lot of regret and a lot of pain. This melancholy touches each of the immortals, but none as poignantly as Kaim. Though the main story is a throwaway, it's the personal stories of Kaim and his band of not-so-merry men that will live on after the last bad guy's been slain.
Combat in Lost Odyssey is about as traditional as you will find in a modern-day game. It is completely turn-based with a menu system that seems taken straight from 1998. Everything you would expect is included. You can attack, use an item, cast magic, or activate a skill. Weapons in Lost Odyssey are pretty boring as none hold any special properties whatsoever -- they are merely an Attack rating and nothing else. And the magic is the same thing you've experienced for the past 20 years. It's based on the elements (earth, fire, wind and water) and uses classic nomenclature to signify more powerful versions of spells.
