Very good hack!
It would be really interresant to integrate a "real-time" battle system where you would see the fights without having to be redirected at each move, perhaps with ajax? It would be interresting also to be able to select a character and see him moving in the battle, I suggest something like you create a "state" system where the rpg administrator would associate each one to some sprites representating a move(by exemple fist attack); all what you would have to do is to play these states depending of the actions choosen by the players in-game.
And thanks for your great work!
