I didn't even realize that you could
my first play through. When I found out you could, I felt like a huge jerk!
Man, everything about that game was awesome. I love how the first half is linear and the second half really opens up. I love all the little tricks, like how you could dispel the Cursed Shield, or the vanish/x-zone trick, or using Phoenix Down on undead enemies, or the special set of equipment for Imp-ed characters, etc etc etc.
My favorite part was turning Setzer into the ultimate killing machine. I gave him the Offering and Genji Glove relics, and equipped him with Fixed Dice and Doom Darts. (Offering normally lets you do 4 attacks at half strength, but since the Fixed Dice aren't based on strength, they do full damage regardless).
Dammit I might need to play it again soon. . .
