Well, Xenosaga 2 had a pretty steep difficulty curve.... but I think Final Fantasy 8 was the worst. I mean, if was just unfair to me when I was 14 and I had enemies that leveled up WITH me. By the time I got to Esther, I just gave up. This floating, winged thing with no legs and a huge chin kept using Ultima on me and I could never win and I had everybody level 99. I just hate that game so much. And how the hell was I supposed to know that you could DRAW summons from Bosses? I just want to kill 'em, not withstand an onslaught of attacks for an ungodly amount of turns, struggling to stay alive so I can steal something that doesn't do s*** for damage when you summon it. Once you're enemies are level 99, a summon that only does 9999 worth of damage doesn't mean a whole lot anymore.
