Look as much as people people froth in their mouth for Final Fantasy VII, this ain't the game if your are looking for romance, like actual romance where both side reacts romantically to each other. The story & gameplay are great, but romance not so much. The emotion in Final Fantasy VII is sadness {the planet is dying and life is miserable}, loss {loss of people and things close to each of the characters Cloud - Zack & Aerith, Tifa - her Dad & her village, Barrett - his crew Jessie, Biggs & Wedge, Aerith - her actual mom who was used as a lab-rat & Zack, Vincent - Lucrecia, Cid - his wish to fly a ship, Red VII - his dad & Yuffie - her people are butchered mercilessly by Shinra to get their hands on Yutai's mako} & maturity {learning to live with their loss and moving ahead} not romance. Cloud is an emotionless wall of a character not only in this game but in every single game that he has appeared in.
