Final Fantasy XI, also known as Final Fantasy XI Online, is a massively multiplayer online role-playing game (MMORPG), developed and published by Square (later Square Enix) as part of the Final Fantasy series. Designed and produced by Hiromichi Tanaka, it was released in Japan on May 16, 2002, for Sony's PlayStation 2, and for Microsoft's Windows-based personal computers in November of that year. The game was the first cross-platform MMORPG and the Xbox 360's first MMORPG. All versions of the game require a monthly subscription to play. Story related gameplay in Final Fantasy XI consists of two major components: missions, through which the main storyline of the game is told, and quests, which do not advance the main storyline, but fill out the game's fantasy world.Completing missions allows a player to advance in rank, which grants access to new areas, several privileges, and various other storylines. At first, a player may only complete missions for his home nation, though they are able to change allegiances later on, allowing access to other nations' storylines. Final Fantasy XI features five playable races known as the "Enlightened Races": Elvaan, Hume, Galka, Mithra and Tarutaru.
