I finished kingdom hearts, for the sake of finishing. Well I got to the end, but I didn't kill Sephiroth, the wraith or Ivory Weapon (my name, not theirs) nor finish all the time trials in the battle arean or get the ultimate weapon.
Amendum: I just killed Ivory weapon, but failed to kill the wraith even with instruction on how. But since I wasn't playing much recently, I wanted to at least do the easy finish.
(damn, I hope they make the sequel, the trailer looks SO COOL!!!)
