Final Fantasy X-2 does a complete 180 from Final Fantasy X's more grounded themes of life, death, and corruption, showing the world after the darkness passes, and featuring an all-female cast of party members. The themes here are much more fun and upbeat, showing Yuna as more on an overall light-hearted journey with her troupe of treasure hunters, although the story does have its moments of seriousness and melancholy. Even the opening CGI cutscene is of Yuna performing a pop song at a concert. It's a risky, but bold and fresh move that you'll either love or hate depending on your tastes.

Final Fantasy X-2's soundtrack is filled with energetic pop songs, pensive ballads, and an overall jazz and rock-inspired sound that matches the game's fun and adventurous themes. "Real Emotion" is an infectiously catchy pop song that would fit right in with the Top 40s charts in real life. "Yuna's Ballad" is much more thought-provoking and emotional, with pianos that sound a lot like how Yuna's sorrow and conflicting emotions would be in musical form. The normal battle theme has a great rock sound to it, mixing in violins to keep things interesting, and it doesn't get old no matter how many times you hear it during normal encounters. The soundtrack is amazing with the way it experiments with different genres that all manage to blend well together.

Set two years after Final Fantasy X, Final Fantasy X-2 is much lighter in tone, featuring Yuna as the main character as she searches for treasure across Spira with her friends. Although the story seems overly positive and campy at first, almost like a cheesy movie with silly one-liners and hammed-up humor, there's much more depth to the story that reveals itself as you play through the game. As a world leader, Yuna tries to do what's expected of her by fixing the power struggle between Spira's two ruling factions, but she's also deeply upset by her love interest's absence. She questions if it's possible to find him with so much mystery surrounding his disappearance. It's an emotional experience watching Yuna struggle with her obligations to maintain peace in the world, and going after what she personally wants for her own happiness and fulfillment.

Final Fantasy X-2 has an exciting turn-based system where you can change jobs on-the-fly. During the fast-paced battles, you can choose to switch jobs to handle different enemy types and situations. When you change your main character Yuna from a gunner to a songstress, she can sing tunes that can debilitate enemies or buff the party for the duration of her song. Character models update to the new job costumes in real-time with special animations, like how Yuna will have a spotlight on her as she poses with a microphone when she changes to her songstress job. It's a fun and unique system that with the way you can swap jobs at any time to handle whatever your enemy throws at you.
