Yoshiyuki Ly said: Barret vs. Dyne is my favorite because of the (mostly negative) impact it left on me. Strange, I know, but it stands out emotionally for me because of that impact.
Blayze said: Not a particular battle, but I had many enjoyable Battle Arena fights, probably still my favourite minigame because of the endless possibilities it could throw up. I remember once ending up against the Serpent with all commands and materia broken, weapon broken and wearing the Minerva Band. That fight seemed to last forever but I was too stubborn to lose all my hard earned points. Other more conventional favourites include Demon Wall, Lost Number, Materia Keeper and the weapon fought near Midgar (Diamond?)
