An i-mode (exclusive to Japan) version of the game was released on November 1, 2011.
In Romancing SaGa 2, the player plays as the Emperor or Empress of Avalon, a castle located in the northwest corner of the game's world map. He or she begins the game as King Leon and later plays as his various heirs down through the years. Leon hands his kingdom over to his son, Gerard. At the end of Gerard's reign and so on, the player is able to choose his or her own successor and pass on Gerard's abilities to them. At the end of each generation, he or she will be given a choice of four heirs. Their identity is based on a combination of chance and anyone whom the player has assisted or allied within in a past generation.
