ok...wow...a lot of comments!

where to start...
First off, I'm focusing on the sprites first, I do have the tidus sprite, but since I have to deal with the palettes of each sprite, I have to recolor certain sprites. An example of this is I don't even have Terra done, even though she is a part of the game. Good news about that is I've only got like three or four more left, I'm half way through Firion right now.
I am going to redo maps, and it is going to be like Zeemis' hack in that perspective, the player will start in the WoR. I plan on redoing maps such as the Phoenix Cave, Gogo's Cave (Zone Eater's Stomach), Umaro's Cave, Kefka's tower and maybe The Cave On/In the Veldt. If possible, when it comes to the Pheonix Cave's events, I'd like to delete the event where you find Locke and replace it with a Boss battle that ends with you getting an esper.
And by a Chaos sprite, I meant sprite sheet. If it was just a monster sprite, I'd do it in a heartbeat.
I've already considered many ways I could to the move sets. As to who gets what, that's a surprise, but rest assured that you won't get anything sh*tty.
Everyone that uses magic, will get Magic specific to what they use in Dissidia FF. Example would be that Bartz gets Holy, but Firion gets Fire, Ice, and Thunder.
Weapons will be the same as magic, I will revamp the entire weapons list and who can equip what. To specialize who can use what magic, I will have characters learn magic through weapons that are specific to them. However, when I release the hack, I will delete all the magic learnable via esper/weapons.
Summons will be exclusive to a hidden character that you will have to find and recruite on your own, also, as I am not a fan of Umaro, he will be deleted from this hack (I will not recruite him in my playthrough, and to make sure no one else does, I will erase the event and one summon [I won't delete Terrato, I like him, so he'll be obtained still, but another esper will be deleted])
