FFLIII takes place in a world where a great flood destroys cities in the past, present, and future. As you control a party of four, consisting of human and mutant classes, you travel through time to collect pieces of the great ship Talon, with the ultimate goal of defeating the enemy responsible for the flood.
The game features a time travel storyline, which means that your actions in one time frame can have consequences in another. Additionally, this version introduces new character mutations and changes to the upgrade system compared to previous Final Fantasy games.
Combat is augmented by items picked up after battles, which can be attached to characters to transform them into monsters or robots, enhancing party power and abilities. This has replaced the traditional experience point system, allowing you to choose which magic stone each character uses, ensuring they never lose it for that specific magic type.
