Man, most of you guys gave it 8 or above, that's crazy. The game was not hard at all for me. No RPG is these days.
KH-5 (not hard at all, even on hard mode) Just beef up!
The hardest game I've played was Xenogears. Of course, I never use guides (unless I'm stuck for months in one spot) on my first play through, and without help on Xenogears or not knowing anything about it, it was damningly hard. Now when I play it, it's smoothe sailing, but that first play through was rough.
