Kingdom Hearts is a walk through the park. Which is why the battles against Sephiroth (and even the Ice Titan) are so annoying because they suddenly require you to strategize and use the abilities in the game that you probably never really paid attention to before because the game is easy enough without them. When I played KHII in hard mode, Demyx gave me a hard time because I would continue to Transform into Shadow Sora and I couldn't deliver a "final hit" on Demyx. I could bring his HP down to critical but he'd heal because nothing SS could do could finish him off. I've received a lot of advice about this battle (and others), but once a game has trained me to think in a certain pattern, it's hard for me to adjust and it just feels like the advice I'm getting is vague and/or completely useless.

FYI, yes, I'm probably the only person left in the world who hasn't been able to defeat Sephiroth.
