ive never done it but after thinking about it, it wouldnt be the hardest of challenges and would be fun. i could definetly do it if aqquiring other GFs wasnt against the rules of the challenge (because GF cards are useful and can get items to teach useful abilties to GFs.) i might do that on my next playthrough. im playing through it again right now but im nearly at disk three again so i wont do this in quite a while. its definetly a challenge ill consider doing because unlike other challenges (solo monk FF1 for example.) its more challenging and less boring.

is it against the rules to aqquire a GF but not equip it? if so ill give it a try but i might just aqquire them anyway.
