I love FFX2 Expansion Set, the features of FFX2 Expansion Set are...
Maximum HP of 61111111 (Not 99999999) for all allies
Maximum MP of 99999 for all allies...
By starting a new game, YRP start at level 999, 61111111 HP, 99999 MP and 255 core stats with all auto-abilities (not elemental strikes)... Now in KH with Gullwings so they Join with Sora, Goofy, Riku and Kairi, you start in Luca, so there is Destiny Island.
I want to dream that FFX2 Game.
