"Final Fantasy II" introduced many elements that would later become staples of the "Final Fantasy" franchise, including chocobos and the recurring character Cid. It also eliminated the traditional experience point leveling system of the previous and later games in the series, instead introducing an activity-based progression system where the characters' statistics increase according to how they are used or acquired. Despite being a sequel to "Final Fantasy", the game includes no characters or locations from the first game. "Final Fantasy II" received little attention at the time from non-Japanese reviewers, though its remakes have garnered favorable reviews.
