Probably learning how to upgrade my PC and installing more RAM and my first 3d graphics card which was a Radeon 9000 AGP.

My most proud gaming moment was when I completed Dying Light. This is because, I have scopophobia which is a phobia where the victim fears being chased. I was proud I managed to face my fear of being chased. I managed to pull this off because I muted my game, and started to listen to soothing Tamil music :D

My proudest gaming moment would have to be when I was a kid and I first beat the caves level in the first tomb raider without my dad’s help. It felt so good to have done it by myself and my dad got me into video games so it really felt like I had made him proud.

Having a sleepover at my friends house (because he had a good pc and a GameCube). I brought Morrowind, and then I spent the whole night practicing SSMB, after which I could kick his ass. Never felt so satisfied before.

My most profound gaming moment came when I got to the end of The Witcher 3 and all the expansions. I'll never forget it. It happened when Geralt looked me in the eyes. I started crying then. And I said, to the darn screen, "Yes, my friend. Indeed, you do."
So, that was also my proudest moment.
Thank you for the best gaming experience I've ever had.

Finishing Eco Quest with my Dad When I was 6 years old. We both worked so hard and my dad was super excited when we finally did it.

My greatest gaming Moment right now is when I defeated a Pokemon Sun Bosses in one shot. I have never done that before. It was so neat to see.

When I finally managed to beat Event 51 in Super Smash Bros. Melee, after hours, and I think even days, of me and friends trying it. ;-)

My proudest moment was when I finally killed the Master in Fallout with a Mad Max build (only allowed shotgun as weapon, leather jacket as armor, and dogmeat as companion). When all was done, seeing the end scene with you and the Overseer, to you walking into the wasteland, was something made me not only feel proud, but made me feel like I conquered the wasteland, and was truly a hero.

My proudest gaming moment was finally beating my older cousin in NBA Live 99 on his computer when I was visiting.

My proudest moment in gaming was when as a young teen in the 90's playing through and completing Myst. That game was nothing like anything else that I had ever played - or that had been made really to that point. I would play for hours on end exploring and working the puzzles. I loved that game then and love it still today 25 or so years later.

One of my proudest gaming moments is when I completed Sonic the Hedgehog with all chaos emeralds for the first time. Completing the game was one thing but colledmcting all the emeralds, whoah.

My proudest gaming moment? Well, most of it was in Terraria. It was when the first time my little brother and I finally beat all of the bosses in Terraria in Master difficulty. We died a lot. There are many of ours graves scattered here and there (in the end we decide to clean it, including the one under the lava, since we don't want Graveyard biome to spawn everywhere). Despite the chaos, we manage to keep every single NPCs alive (of course, except the Guide, it was inevitable), and that's something we are proud of too. Since we already feel attach to them. We even call them by their names, and not professions. Anyway, before we defeat the last boss, Moon Lord, we also manange to build three railroads with their own multiple stations (one is a hell bridge down in the underworld, the one other is a subway between the underground and cavern, and another one is a skybridge up in the sky), a massive elevator (a hellevator and skylift combined) that connects those three railroads, several outpost towers, and a fortified town on each habitable major biome. Knowing what we built is functional as intended is the best part of it.

My proudest was when i completed Diablo 2, When i was a kid

My proudest gaming moment I think was eventually defeating all the Weapons in Final Fantasy VII and collecting all the hidden Summon Materia after months and months of playing the game.
