Don't write bad reviews just because there isn't a spiky haired guy in the cover.
Only too many people have already judged Final Fantasy X-2, based on very lacking information. People who oppose this game usually have a stupid and retarded opinion of having to have a Square tradition of non sequencial Final Fantasy games. They also think that the characters and the setting are the same, making the game boring. However, like said before, many people who remark with such useless comments don't have enough information. This game is awarded with an extremely high score, even just based on storyline.
The gameplay's a little bit different. No more Aeons, no more Overdrives, and no Overkills. However, the Aeon command has been replaced with the "Change Dress" command, where the character changes their Dress Sphere into a different one, taking on a job of a different position. A good example may be from White Mage to Dark Knight, and so on (by the way, these "Dress Spheres" determine the character's HP, Strenght, and etc.). Yuna has also been given the ability to do some extra things on the field (something like... jumping?).
The music has been replaced completely. If you're expecting the old tunes from Final Fantasy X, forget it. The composer is not Nobuo Uematsu, but two new directors. The music differences seems to be quite large however. Songs like "Shuin's Theme" or "Memory of Lightwaves" seem like something that may have been the work similar to of Nobuo Uematsu, but the new Blitzball theme and others take on a complete new genre of retro.
The replay value is very high for Final Fantasy X-2 as well. Because there are multiple endings that come to totally different results (and I mean, TOTALLY different results). Also, there are a lot of side quests and optional missions that can determine the outcome of the game (wow, isn't that neat? You get some control over the chronological order of the game).
Character depths are quite deep as well, which ties in perfectly with the storyline of twists and turns. Scenes like Yuna and Tidus being shot to death wreck a high shocking curiousity from the gamer (as well as suspense) while scenes like a familiar friend of Yuna (or is it him?? I won't give it away..) embracing her gives a sense of retrospection and nostalgia.
I do have a few disappointments about this game, however. It seems to have a slight touch of nudity, probably in order to pull in a lot of male gamers. As you've probably heard over and over again, the "Dress" feature does involve the transformation of the female characters which goes through the process of them having some flesh shown while the new clothes appear over the old. However, it's actually not as bad as everyone says. I have watched 6 trailers so far, and the dress scenes do not show much detail.
Lastly, for those reviewers who have maliciously attacked this game, I would recommend that you watch some trailers, and at least get the basic grip of it (I read some of the reviews, and it just made me laugh over the way how they were talking over the game with the one or two facts they have about the game. I even read one review that complained "Where's Tidus anyway? He's the hero of the story.." Lol...).
I've tried my best to give a good description over the game, but what the heck? If you want to buy the game, buy it. If you think it's really stupid and that Square shouldn't have released a sequel, then don't buy it! It's that simple! No need to go round about complaining about how stupid the game is. And as for my rating of 8.2, I'd love to rate it a 10, but I have to be fair. Although I have tons of info over the game, I have only recently beaten it myself.
