Who wouldn't want to live life like in a Japanese role-playing game? You get to be a punky, headstrong kid, with colourful, spiky hair who travels through magical lands, has adventures, and collects progressively more impressive swords along the way.
To a large extent Children of Mana fulfils this brief admirably. Evil is corrupting the island of Illusia, mysterious columns of light have appeared throughout the land, and monsters are amok. It's up to you to reclaim the land, one dungeon at a time.
