I use the same exact party and lets just say that with a triangle attack i can hit for over 3k with Xenogears and while Bart only does a few hundred with regular attacks, Citan(the guy in green) can attack for over 6k. Leveling up may come in handy and you only get some Angel AR every now and then but you get alot of AP and money too(though i already have over 500k). I haven't really leveled the others up though. Oh, make sure to visit the light house which is near the middle of the world map as there is some good stuff to be found including a little to the story. Also be sure to take that nano-girl(i forget her name) with you as she'll experience a little "growing up" of her own. Well, i hope that you all enjoy posting and have fun gaming.
