well in my opinion, this one and the XAS one (made by the same scripter BTW) are the most complex battle system out there.
I mean yeah this script is a pain in the ass after all, like humm 100 frames for only ONE pg in the battle (i know you can customize the number of frames but if you do like RTAB (40 frames) it would be bullshit).
But hey if you want to make a SERIOUS game with a very fluid animation and a very funny game, you should definitly use this.
I mean, with a lot of scripting you can do ADD-ONS like your own HUD etc, making your game like TOP for the ps1/gba!
I'm not the guy who know scripting wery well (i don't know script after all the last time i scripted something was in the 2005)
But in the right hands... this script would be amazing. Someone should contact Moghunter (the one who took care of XAS)
