Weirded win ever.
I think I've got one on ya, I always love to tell this one.
Final boss in FF9, Necron, the stat ailment dick. I got him about half to 2/3rds down, and then had Vivi petrified, Garnet dead, Freya frozen, with Zydane berserked. Anyway, I put the controller down and watched as berserk Zydane single-handedly beat the ever-loving shit out of Necron and won the game for me. I didn't know whether to be happy or pissed off!
I beat Necron with Garnet and Vivi alone. Everyone else was dead. It was amazing. Best win ever.
