VI: Kefka's "self-help booklet" line, priceless

VII: Climbing the stairs of Shinra tower, with Barrett's constant moaning, (SPOILER)coming to Aeris' home village after her death, and seeing flashbacks of her parents - a very eerie moment

VIII: The opening FMV, the whole ending (especially the moment when the FMV fades to the credits and the traditional FF theme begins - also the camcorder part of the ending as the credits roll) - I'm a big FFVIII fan basically

IX: (SPOILER)The destruction of all the main cities: Cleyra, Lindblum, Alexandria - anything to do with Quina, and the ending again(SPOILER)Vivi's letter is very sad

X: (SPOILER)Discovering the rotten truth behind Yevon, and the lies behind the Final Summoning
