I haven't played most Final Fantasies, since I don't have them or their systems....
But my dad has FF8, and I actually got farther than he did and beat the game(he only ever got to the beginning of disc 3)...
Yes, Tonberries are Scary. I was scared out of my wits whenever one shown up... where Odin is(forgot the place's name)... But still we had to constantly fight tons of tonberrys to get Tonberry King to come out and play.... That was definitely my Most Annoying Moment.....
That, and how just when I thought I beat Ultimecia, she changed forms again...then again....then again....
