If by hunting you mean marks then yes I hunt often and am currently stuck on Fafnir...(bastard)

I try to ignore game hunting but its so cool when you are just randomly traveling and suddenly you are standing face to face with the once-upon-a-time-invisible Wood Toad.(That things a BEAST)

Due to a bad experience when I first played, I feel I have to hunt the rare game. You see, when I first started I wandered off into the westersands and was sticking to a cliffside when all of the sudden a ghost came out of nowhere and pwnalated my entire team...(Which is not saying much beacause I was out of items and only had Vaan.) However I still go out on chocobo and look for that same enemy and have never again seen it.

Speeking of rare game, anyone ever faught a Crystal Knight in the great crystal. They are only a rarity of one but they are tough!
