My story comes from
Kingdom Hearts as well. I'm sure people who played the game remember the boss battle in which you face the dragon Maleficient. In my opinion, this is the hardest battle in the game, especially since the dragon cheats with its flame attack and continuously spins its tail. It took me 6 tries to figure out how to get close to his one and only vulnerable point: his mouth, where the extremely damaging flame comes from. I think on my 8 try, I finally beat him, but at after that I was just too tired to continue with the story, and just turned of my PS2.
Even Ansem wasn't this hard!
...My most frustrating experience.
