A few big changes mark the jump from GameCube to PS2. Once you got married in the GameCube version, you were guaranteed to have a boy child; in this version, you may have either a boy or a girl. The GameCube version featured three possible wives for the main character; the PS2 version bumps this up to four, with Lumina now joining the list of potential targets. Finally, the length of play seems to be up considerably for the PS2 version, as once the main six chapters that comprise the game's storyline ends, you're free to continue building your farm as long as you want.
In addition to these gameplay changes, a new theme song is being prepared for the game. J-Pop group Dreams Come True will perform their hit "A Little Waltz" for the theme song in Oh! Wonderful Life, which should add a bit to the presentation of the game.
