Suprisingly, even though FOP is TV-Y7 and KH is E10+, the series is rated TV-MA/M17+ for strong language, intense violence, blood and gore, sexual references, use of alcahol, tobacco, and drugs, strong lyrics, and highly suggestive themes.

Cosmo, Wanda and Poof's memory lives on within Timmy's Keyblade, the Wishmaker. This gives the group the ability to preform special moves called Big Wishes. The starting ones for each character are:
TIMMY: Cleft, The Boy Chin Wonder: Timmy turns into Cleft. He can't be damaged, and his attacks do 50% more damage. Lasts 30 seconds.
ROY: Phantom Lord: Roy envelops a whole area in darkness, and kills all the enemies in that area in a matter of seconds. It will fail if no enemies are enveloped.
SORA: Hyper Beam: Sora fires an all-consuming beam of light from his Keyblade. He can be hurt while firing it.
KAIRI: Bloody Valentine: Kairi carves a large heart into the ground, jumps up, and slams her Keyblade back down, killing all enemies within the heart. Similar to Phantom Lord, but it can't fail.
If you have a Guitar Hero or Rock Band controller, you can choose to fight bosses with music. Roy plays vocals and rhythm guitar on songs that require it, Sora plays guitar, Kairi plays drums, and Timmy plays bass. You get a choice of three songs per boss. The toughness of the song varies by where the boss is in the game. For example, Francis is the first boss in the game, so you get a choice of very easy songs, such as "Fascination Street" by The Cure on guitar. The final battle against Vicky, Xehanort and the Brotherhood Of Evil has very hard songs. For this battle, you have only one choice. On all instruments except vocals (Roy plays rhythm guitar), the song is an original piece named "Idiot", and it is labeled as being recorded by the New World Order. It is 9 minutes and 30 seconds of some of the hardest guitar, bass and drum parts in history. As for vocals, you have to sing Queen's "Bohemian Rhapsody", which is half as long but as hard as Idiot.
- Roy's Big Wishes (except for Wrath Of The Seventh Sin) are all named after metal, punk, and alternative songs.
- One of Roy's phrases while unleashing a Big Wish is, "Peace sells... BUT WHO'S BUYING?!" This is a referance to Megadeth song "Peace Sells".
- Vicky's last name is Manson. This is a reference to notorious murderer Charles Manson.
- When Happy Peppy Gary offers Sora a soy cube, he says "Stick it up your-", but Kairi covers his mouth and sighs, "Bad idea." The fact that Sora doesn't say "ass" could be a reference to Limp Bizkit's song "Nookie".
- In the music boss battle for "Idiot", a heavy version of the intro of Dragonforce's "Through The Fire And Flames" is used as the interlude.
