Man that list is pretty big for me ^^; I'm just going to name games and segments and hope you all can figure it out :x

Secret of Mana, executing level 8 magic and getting that cool effect, that one theme song near the end of the game. 

Chrono Trigger: Several of the songs played at perfect times and gave me shivers, some of the double-triple techs gave me that omg feeling, flying the Epoch into lavos and having it go into first person in that weird time-space area :3, game intro around the part Chrono does Ice - sword on the skeleton dude, the music just times perfectly with the scene xD, getting a critical hit with Chrono (best noise ever!). *sigh* pretty much everything about this game xD

FF6: Operah house song, sad theme for that dead chick (forgot her name ;-;)

Legend of Zelda a Link to the past: Using the "Bombos" magic for the first time, Deflecting the fireballs from Ganon, the peaceful city theme (forgot the name :x ), that sound the Master Sword makes when you swing @full life.

Legend of Zelda Ocarina of Time: Becoming and Adult, getting to use the Mirror shield on the Witch, Getting Big-goron Sword / Red tuinc :D

Smash Brothers: Finally learning fox after using Pikachu for so long ^^ it made the game feel worlds different.

Mario 64: Ending Song. 

Wild Arms: Opening cutscene, music. 

Metal Gear Solid: So many story related moments it's not even funny ><; Definitely when Sniper Wolf died. I cried ;-;

FF7: Omnislash for the first time, any level 3 magic with all materia for the first time, Aeris's theme, all of the CG cutscenes gave me that sense of amazement, that final duel with Sephiroth (I didn't like him much as an enemy, but that last scene was so badass). And of course, Sephiroth in the fire is very notable xD

Chrono Cross: Cutscenes, Music, Seeing chrono-luca-marle :3, Using Luminare for the first time, same with X-strike :D 

FF8: Cutscenes again, Julia's piano theme, any scene that focused on Quistis (mmmmmm she's a hottie xD) almost every GF summon.

FF9: Cutscenes ;) Best in the series in my opinion, Esper Summons... thats it xD

Devil May Cry: Throwing a chain of combo's together was incredibly rewarding, Getting the Sparta Sword and just raping everything and their mothers, Hitting devil trigger with the pistols and spraying lightning everywhere :3, some of those cutscenes were amazing also ESP the first spider one.

Zone of the Enders 2: Vector Canon and Zero Shift! (enough said ^^ )

Final Fantasy X: The ending was soooo soooo sad...

Xenosaga: Anything KOS-MOS gave me goosebumps.

GOD OF WAR!!!!!! Starting the game up with my friend hating it so much for stealing DMC's title as best action game, then watching my friend fight through the first stage and nearly shitting myself from too much awesome. The cinematography and art design of this game is without equal :3 The moment Kratos lept off the hydra's head and the camera panned downward as it showed the massive hydra lunge over the top of the ship to swallow you whole I knew I was in love. Almost everything about this game gave me shivers and made me feel god-like :D

God of war 2!!!!!!! Everything about the first one only - the Hydra :D, some amazing feeling while playing ^^

Soul Caliber 3, realizing what the game was actually about all along, Asteroth and Ring-outs :) Some epic duals with my other friend who's great at Ring-outs ^^ (damn you sigfried!)

Shadow of the Colossus: This is when I realized what Video games could be, and that realization was enormous ^^ I saw my friend fighting the really tall vertical dude and was just absolutely taken away by what technology had become in videogames :) 

THIS GENERATION!!!!

This has to be my favorite generation for gaming by far! The bar has raised so high and everything is just out of this world amazing ^_^

Gears of war was OOZING next gen when I first saw it :) Incredibly detailed textures, just great overall motion to the game, I was impressed :)

Bioshock: The water in the opening scene was just out of this world! Definitely another eye opener ^^ 

Assassins Creed: Mainly environmental graphics/lookout points but they were still gorgeous ^^ 

Heavenly Sword: Absolutely INCREDIBLE facial capture, I've never felt so connected to a game via graphics, the environments were breath taking, the cut-scenes were insanely phenomenal, and Nariko was sooooo hot sometimes :3.

Ratchet and Clank: This is where "Next Gen" really started for me. I watched the opening Cut-scene in the demo to see if it really was on par with "Pixar level animation" and I will say it was close, but not quite, so I sighed and said oh well and continued to watch, then when the cutscene ended and the graphics suddenly got BETTER I was thinking this is more like it! Then when I realized that I'd been standing around for 30 seconds while the game itself had loaded I was absolutely breath-taken. I didn't think it was possible for a game to look so good, yet Insomniac proved me wrong :)

Resistance Fall of Man: Tagging something with a Bullseye is probably the best feeling experience I've ever had with a Digital Gun. The moment you hear that little "beeb beeb" you know someone is about to be raped HARD by a spray of bullets from a well covered position.  AIR FUEL grenades are the best grenades I've ever thrown in a video game :D

Super Stardust HD: I've played similar games, but nothing on the caliber that I've seen from this game :) So fluid, so fast paced, so many particle effects on screen. DEFINITELY breath taking to play :)

Uncharted Drakes fortune: Another example of Story Telling in an absolutely insanely believable way. The prettiest console game I've ever played in terms of environments. So many times I had to just stop and look around. The lighting was so good, the textures were phenomenal, and the overall animation was just great ^^

 Theres probably many more but these all came off the top of my head instantly ^^

@crono--"Bioshock: The water in the opening scene was just out of this world! Definitely another eye opener "

it was nice till you looked at the plane and saw the crappy foam spary....that ruined the whole experience

The main one recently (there have been heaps over time) has been surprisingly from Elite Beat Agents.

I was really really moved when playing the song 'Inspiration', it was just a single moment of actually being touched that I hadn't felt before while playing that game.

LOL @ Mesoteto so true xD but that water!

ohh i know i loved seeing the light from the moon and i was all into the flame....them ......yeah...i seriously wanted to drive over to the game devs house and punch him in the face---did you notice it popped up alot--like the door that burst its awesome flowing in then that spray effect again!!!!!!

Twilight Princess. Several times... I don't want to spoil anything, but especially on something that happens toward the end.

^not sure but i heard that in the final fight if you pull out your fishing pole a certain someone get all mesmerized and wont fight for a bit.......never tried it

 :D They were the most impacting fom me xD They just made verything warm and fuzzy :3

The ending of MGS3. Where snake is standing in front of The Boss her grave. And the MGS theme is playing.
What also shocked was Alyx getting stamped on by hunter in half-life 2.
Remake RE 1 scared the hell out of me. The atmosphere of Medievil (AWESOME)! And shivers when i tried to save kratos his family with kratos, the music in that part is awesome (called: Zeus wrath divine) And the end battle with zeus in God of War 2.
