GT3 when I saw that one for the first time, I was deeply impressed.

I'll probably come up with many, but the first one is on Golden Eye.

   It's actually a memorable moment, rather than the fondest moment.  I was playing a regular death match (or whatever is was called back on Golden Eye) with friends on one shot kill. I had the RCP90 with the seriously fast rapid fire. I came around a corner and saw the back of my friend, who was facing a wall. From what would be a few feet away, I unloaded on him. My friend turned around and saw me. I am still firing away at almost point blank range, and somehow, NONE of the bullets are connecting. The dude points his terribly slow magnum at me, and I'm still firing like crazy, he shots once and I'm dead. My friend turns around to look at the wall behind him, and it's a blanket of bullet holes just covering the wall. I tell you, that game cheated for him.

My best memories are mostly from the Arcade. The glorious trippy mushrooms in Space Harrier, 'let's go mr driver' in Chase HQ, chucking ninja stars and the awesome music in Shinobi, the HUGE stage 3 boss in R-Type. I could go on all night - happy days :).

I had a very similar reaction to Mario 64, but the thing I have to put as my fondest moment in video games was the ending of FF X because I really really expected a happy ending after the whole love story thing and all that, but then the way it ended I loved how it was the complete opposite of a love story happy ending kinda thing... You know even some movies don't dare venture outside of happy endings, and for a video game to do that has just got to be respected.

it's gotta be the first time i saw knights of the round table in FF7. just ultra powerful attack, i was like "whoa"

My fondest moments are probably the nights I spend on the original Tomb Raider, playing into the early morning hours and being shocked at how quickly the hours went by. Truly an incredible game. Another would have to be playing Capture the Flag on the level Face in Unreal Tournament. Quite possibly one of the best designed Capture the Flag levels ever. I probably played over 1,200 hours on just that one level.

I have also similar memories about the 3D games, but they killed my favourite genre the 2D platformer so I can't call it my favourite because it's been jaded by that. I also really enjoyed the first level of Sonic Adventure on Dreamcast, that was epic enjoyable. The first memory that comes to mind has to be acheiving super sonic form in Sonic 2, that was a fucken hard challenge back then and it was SOOO worth acheiving... I never wanted to turn my console off. But I think the ultimate memory for me just lies in being a gamer when I was a kid, going around to friends places and beating games like Mario Bros 3, Mortal Kombat, Street Fighter 2, UN Squadron, Sonic, Super Mario World and Donkey Kong Country's I think will stick in my mind as some of the most enjoyable times of my life :)

Oh... I also liked when Link first pulled the sword out of the stone and turned old in Ocarina of time... I didn't know that he turned older when I did that (yes I sheltered myself from that game and any news about it completely until I played it).

Wow, I totally just remembered that feeling of playing that level. Utter awe. Everything about it was just beautiful. For me at least, it was all the more satisfying because the first 3 copies I got of that game were defective. I couldn't play my brand new DC on the first night I got it! Finally I got a working copy on my 4th attempt and the rest was history.

For a while, I kept a copy of my saved game at that spot, so that I could watch the scene where Link opens the door.  That was some good direction right there.
