Mine would have to be the training. I just love it when i played FF7, there was a boss halfway through the first disk, the one that used Trine (cant remember the name). Anyway, i tried beating him the first time and he wipes out my entire party with one attack. So i was a little peeved after that, so i ended up training rigorously next to the save point, almost so much that i wanted to have Eye Of The Tiger going in the background. So after an hour of training, i had gotten... 4 levels.
...
whoo... so i try to go and fight the thing, it does the same attack and does about 1/6 of my characters hp. So i retaliate, and i do almost half its hp. So that kinda pissed me off because it was only that one attack, which it only starts the battle off with. So if you can survive that, you can be level 1 and kill it.
...It was REALLY annoying...
