Favorite aspect of FF6 hacking

I'd like to put almost everything, but music takes forever to be finished; dialogues most of the times means full game hack and so tracking down dialogues among thousands elements(and i don't know the exact position of each map dialogue in the list) ; events are great, but just thinking at moving many actors at the same time and fragmenting their queue in tons of little queue for each step... ;[
Finally the map is even more great, but i start a fight with the editor just to place properly layer 1 and 2 on a 4x4 tile piece of map

PS. while among choices i also voted spriting, inside that choice it's not included actors sprites, i definitively like most static ones, like monsters.
