Hah... in Aus they didn't release the VMU's so we had to wait 2 months to get them... i reckon i've played the first level of sonic 100's of times. During the online ranking competition I was ranked number 3 for australia at one stage (until people starting cheating and bouncing off the nose of the killer whale). Ahhh jeez i loved that LEVEL (the rest of the game was kinda sucky :P)

Playing Starwing on SNES.  Finishing  SF 2  with a spinning piledriver  with Zangief.  The ending of Majora's Mask.

Unlocking the secret ending in eternal darkness. Good times. 

the first time i beat super mario world on the snes and beatin that 1 snes game that came in a black cartridge i think it was made by rare

Too many to mention and mostly in my early teens when I had real passion for video games.

Getting banned from an arcade when I was 12 for spending 18 hours on guantlet with one 10p credit.

Getting 9,999,990 on bubble bobble with 1 credit, despite the official record being much lower.

Finishing Marble madness dripping in sweat with hands covered in blisters.

I think that each gen blow me away with a game, but the most memorable is still the first one >> my first gaming console the SNES with DKC! WOW!! The game with it's graphics still amazes me these days! The last time I replayed the game when it was released on GBA I was like a kid! Sweet time. Zelda: OoT, Mario 64, Zelda TP, Gran Turismo, Sonic Adventure on the DC (well, mostly the first level...), Metroid Prime and Metal Slug 3 on Arcade just had that WOW effect on me.

it would have to be all the hours, blood, sweat and tears i poured into GT3 not to mention all the battles i had with my freinds on it

completing The Legend of Zelda, Ocarina of time... good Memories :P

 This one isn't incredibly high on my super awesome moments list, but in all seriousness, best FMV in any Final Fantasy is when Alexander comes alive in Final Fantasy IX and owns Bahamut subsequently causing my head to a'splode.

Shadow of the Colossus' ending was also ridiculously amazing. 

Well, the thing that sticks out in my mind is the first time I played Scorched Earth of all things. It was hilarious for some reason. Next up is the very first time I played Red Alert 2, great game. Hmmm, the final stage of Contra III was pretty intense. Perfect Dark multiplayer againt perfect sims was also very intense.

Sonic Adventure. I don't care what other people may think, I personally like it 100 times more than Sonic Adventure 2. I didn't like that game very much. It was those Tails/Eggman and Knuckles/Rouge levels that severely ruined the experience.
