That was a terrible list... Seriously, Jecht turning out to be Sin is a "cool moment" and not just Square pulling out one of the oldest story cliches in modern writing? smurf you.

Here's my list:

FFII - Emperor Mateus comes back from Hell as it's new Demon King: Seriously, while the fake out death of a villain is pretty normal in games, it's not very often you actually kill the main villain only for him to come back to life and now as a freaking eldritch king. I don't think any other villain in the series gave you as much of a "I'm smurfed" sensation than that moment.

FFIII - The Dark Warriors sacrifice their lives to help the Light Warriors defeat Cloud of Darkness: It comes out of nowhere that the former heroes of the world would come to the rescue and help weaken her enough for your party to actually mount a real comeback against her.

FFIV - Cecil undertakes the trial and becomes a Paladin: Dear god, it's like one of the most iconic scenes not just in FFIV but in the FF history itself. It's an emotional scene that finally allows Cecil to realize that whining around about his past mistakes will not give him closure but rather he needs to redeem himself through action. The fight itself was really clever as well since it seems counter-intuitive to not attack his dark self.

FFV - Galuf's heroic sacrifice: PURE AWESOME ADRENALINE...

FFVI - The Opera Scene: Not only did an opera house feel completely foriegn to be in an RPG but to turn around and actually build a mini-game into it by expecting the player to perform in it? Unheard of and it's probably one of the many reasons this scene is so famous in the franchise. It also allowed us to see both a softer and more human side to Celes who up until now was just the Ex-General turned good guy and it would be this moment that makes the whol love story sub-plot more apparent to the player but also lead to several of Celes' most defining story moments in the game.

FFVII - The Opening: Aerith's death is overrated and god knows I didn't cry. Instead I feel the opening is the best choice cause it really is the best opening in terms of showing off a technical know how of the hardware but it also explains absolutely nothing to the player so creates a sense of intrigue that makes the action packed first dungeon a real roller coaster ride for the player. If only the rest of the game was as well thought out...

FFVIII - Assassinate Edea: Granted a lot of the excitiment is due to some poor usage of the Idiot Ball being passed around to the cast like a case of herpies but it does include into a nice mix of viusal feast, and watching Squall be a badass and steal a car, single handidly storm Edea's float, bitch slap Seifer, and then battle the Sorceress leading to her impaling Squall and thinking he might actually be dead, and then the game asks you to switch discs. Seriously, I don't think any of the PSX FFs had the player scrambling to change discs so they can find out what happened as badly as this scene did.

FFIX - Battle Against Black Waltz #3: It's a cool action packed scene filled with heartbreak and awesomness, Vivi pretty much solidifies his immortality within the fanbase for this awesome sequence of events.

FFIX - Bahamut vs. Alexander: This scene is pure fan service but also I just find it nice to witness a CGI cutscene of awesomness dealing with two of the most iconic summons in the series actually duking it out in full glory. It's a great tribute, not just to the series, but to the fans themselves who would appreciate this scene for more than just it's story context.

FFXII - The Sun-Cryst at Pharos: Dear god, this scene is really the ultimate fulfillment of the emotional story of the games three best characters. Ashe finally reaches the end of her journey and makes her choice that has been the heart of the games story, Balthier finally confronts his dad and gets the closest thing to closure we'll ever see, and Basch gets to verbally bitch slap Gabranth by showing that he's better than him by taking the high road and staying faithful to his ideals. Not to mention we get a heroic sacrifice and some awesome boss battles, it's really no wonder most fns can't help but question why this wasn't the end of the game.
