Final Fantasy II is a fantasy role-playing video game developed and published by Square in 1988 for the Family Computer as the second installment of the Final Fantasy series. The game has received numerous enhanced remakes for the WonderSwan Color, the PlayStation, the Game Boy Advance, the PlayStation Portable, iOS, Android and Windows. As neither this game nor Final Fantasy III were initially released outside Japan, Final Fantasy IV was originally released in North America as Final Fantasy II, so as not to confuse players. Following enhanced versions for iOS and Android in 2010 and 2012 respectively, the game was re-released again as part of the 2021 Final Fantasy Pixel Remaster series.
