Final Fantasy X has a hidden affection point system that changes the final Overdrive for Tidus, allowing players to choose their favorite female character, before being railroaded to the conclusion of the story. FF8 was the first entry in the series to be centered around a love story, but FF10 also had a strong focus on romance, with the blossoming love between Tidus and Yuna becoming an important part of the story. The disappearance of Tidus at the end of FF10 then directly ties into the events of the sequel, with Yuna going on a quest to save him.
FF7 introduced an affection point system to the series, where the player's actions would determine which character Cloud would go on a date with at the Gold Saucer. The FF7 dating mechanics & romance system involved a points system, where the player's choices in dialogue would show their preference toward the characters. Once the story reaches the Gold Saucer, the character with the highest affection points will go on the date with Cloud, with the possible choices being Aerith, Tifa, Yuffie, and even Barret.

Tidus might be a great blitzball player, but he still needs help from his party.
