My cousin came over to my other cousin's house one day. I watched her re-playing some scenes in kh1 with her save files. I saw Squall speaking so I continued to watch.
Worst moment? In the first game, that would have to be Evil Riku battles, Maleficent as a dragon, Monstro's chambers and Ursola's cauldron thing... I really sucked at battles back then, okay?!
Second game would have to be Xigbar. Damn his guns. Then there's the reaper in Port Royal. Took me a while to beat the damned thing.
Xigbar fight in proud mode. I nearly gave up on that part. I was lucky to have Final Form pop up in that fight!
Then there's the Groundshaker boss in Pride Lands which was also in proud mode.
Finally, we have the journal entries. I suck at mini-games. Can't do the one in Twilight Town where you have to push the bag to the garage before 16 or so seconds.
Could be just me but air combos work good against bosses. I could just juggle(is that the right term?) them from there, beating them after a while... most of the time.
