Now in full color! Final Fantasy Legend DX operates on a turn-based system. The game's characters battle monsters and fiends using a variety of weapons, armor, and skills that develop through the player's actions. The game follows the story of four heroes who attempt to scale a tower at the center of the world that supposedly leads to paradise. The four heroes may belong to one of three character classes, each housing a unique customization path. Final Fantasy Legend takes place on several worlds centered around a large tower, built by the Creator in ancient times to link worlds. There are four unique major worlds that make up different layers of the tower: the World of Continent at the base, the World of Ocean on the 5th floor, the World of Sky on the 10th, and the World of Ruins on the 16th. Time does not flow at a constant pace between levels of the tower, rendering some worlds more technologically advanced than others. Various monsters come forth from the tower into each world. Many are hostile, but some of them are friendly to humans and willing to coexist. An offshoot of the human race (named mutants, espers in the Japanese version) also exists in each world; they are the magic-attuned descendants of a union between humans and the World of Continent's older races. The World of Continent is a large land mass ruled by three kings in constant war for control of their world. They each carry an object needed to open the tower's entrance. The World of Ocean consists of various small islands surrounded by water, each connected by small caves. Pirates roam the sea of this world, forbidding travel by ship. The World of Sky contains large land masses suspended in clouds, and is ruled by a powerful dictator from his flying castle. The World of Ruins is a technologically advanced cityscape, reduced to a post-apocalyptic wasteland by constant monster attacks.
