Other things similar to a difficulty level is the introduction of an Expert level Sphere Grid in Final Fantasy X PAL, HD Remaster, and International Versions, and the different New Game Plus modes in Final Fantasy XII International Zodiac Job System. Some Final Fantasy XIV battles have a normal and "hard" version, the normal version being the only required for storyline purposes. Notably, the original North American release of Final Fantasy IV was made easier than the Japanese version, and is often referred to as the Easy Type version.
