The first time playing without knowing anything about the world , also how much dead money used to scare me

The title should be "your fondest MEMORIES in any Fallout game", because I have a whole bunch of memories in the games. And it's kinda hard to pick one over the others.

Well, the oldest one I can recall is when I discovered Fallout 3. I was at a friend's house, and he was playing the game, and I was just amazed by the game. He kindly let me start a new character just for fun, and after that I was like: "I HAVE TO GET THAT DAMN GAME". Bought the game and played the shit out of it. This brings me to another great memory from the game: joining the Brotherhood of Steel for the 1st time. It was quite amazing for me, all those people wearing badass power armor, in their huge fortress.

Now, switching to New Vegas, the game didn't striked me much the 1st time I played it. And I honestly didn't liked it much, until I started modding it, and discovered the someguy2000's serie. From straight to finish, this quest mods series just blew my mind, it was even better the base game story. So, my fondest memory from New Vegas is playing this insanely good story.

My best memory is playing Honest Hearts, the scenery is absolutely beautiful, along with Old World Blues. But I really got into Honest Hearts, due to the tribes battling with each other. It was great, I have many fond memory's with the standalone game, with my first playthrough being 'Yes Man'. It was amazing.

my fondest memory is of playing the game in front of my family and them asking me how I play it since it looks so "depressing".

lol I was on the quest with the cannibals in FO3 too to scare them away that little more.

I have countless moments like this

One off the top of my head was when I first confronted/defeated Father Elijah in Dead Money and entered the vault with all the gold.

After experiencing that and heading for the exit of the sierra madre, knowing I was about to leave it all behind, I felt emotionally immersed into a game for the first time in my life

pretty deep shit right?

Shooting Allistair Tenpenny and his goon Mr. Birk in the face

My fondest moment is killing my first Deathclaw,I always hated those things along with Cazadors nasty buggers,But killing them and getting my first kill on them after countless deaths is a great moment.

it has to be nuking megaton for sure

Flipping the bird at the Big MT scientists.

"GREAT. NOW THE PENIS ON ITS HAND IS ACHIEVING ERECTION."

My fondest memory was back in Fallout 3 when i entered a subway for the first time and saw my first group of ghouls, they charged me and i had a heart attack and ran out of the subway. That was the moment i knew i would love this franchise.

The ending of Fallout 3 when I first played it. I like the Concept of the ending rather than the actual ending. You come full circle with your journey, Father sacrifice himself for you, and then You sacrifice yourself for pure water - as you remember the bible quote and use it as the password. (that code idea was cool since there was no guide for it). It sounds good on paper but... meh. Boss was disappointing and Sarah did most of the work.

Killing benny is one of the best moments I had

Fighting Father Elijah with the good ending. The idea that Dean and Christina were helping in the ensuing fight with the good ending was so cool. I also liked having to decide between the gold or my life.

In the end, Elijah was a prick! But for some reason, I always hoped he'd come back. Such a great villain, I loved how he was established in the game prior to the DLC. That's how you set up a side story Bethesda!

in fallout new vegas imagine this
you walked the road to Zion ,managed to purge the valley of white legs out of zion but sparing their leader as a testament to my mercy and showing the dead horses that even the worst men deserve mercy
youve walked the big mt and found all the technology and sciences you could ever need or want
youve walked the villa and robbed the sierra madre blind and learned not to let go while saving your partners in the biggest heist of all time
you finally reach the divide and walk the road alone ,you finally meet the man behind the note Ulysses a wise and honorable man holding to good ideals and finally
you are on the dam
its pouring rain
you've completed every ncr or independent quest you could do
you've completed the entirety of someguy2000s bounties mods and suffered at frosthill having avenged your boss and friend
you storm the legions camp with nothing but sweet revenge and 1500 rounds of .44 ammo
you slaughter every legionnaire with the help of the  Enclave remnants
when you finally get to Legate Lanius you blow his brains out with a few well placed shots in vats and walk off with his helmet talk to yesman or general oliver sealing the fate of the wasteland for the better
thats my fondest memory and is why i love the developers of new vegas and the mod authors who created such a story

I remeber the first days of playing fallout 3, i just liked how the power armor looked on the cover of the case, i was like nine or ten, i was so amazed at the game at the time, the music, the atmosphere, and everything else. i fell in love, i couldn't stop playing it. I then got new Vegas on my laptop and messed around with mods in early 2012, i was almost 13 at the time. thats all i can remember.

I just completed Fallout 4 for the fifth time. My first playthrough with the Institute had me take down the Prydwen and after I'd destroyed it Atom Bomb Baby started playing on the radio. I thought it was quite epic and made me feel like a total badass.

Anyway, after completing the BoS ending for the second time and tuning to DCR right after I'd destroyed the Institute, I heard "I don't want to set the world on fire" by the Ink Spots. Needless to say, I nearly cried being my Fallout 3 memories combined with the killing of my son and all.

I love Fallout 4's scripted song events.

Strangely enough, my fondest memory out of any Fallout game came from perhaps the game I dislike the most — Fallout 3. A lot of things were done so wrong in this game, but atmosphere was certainly not one of them. I'll never forget the feeling I had when I first emerged from the depths of Vault 101, only to be blinded by sunlight and exposed to a beautiful landscape. I'll never forget traversing that landscape, and entering Megaton for the first time an being absolutely astounded and amazed at the gates, the sights, the sounds, the city itself. Simm's first lines eternally play in my head.

My fondest Fallout memory comes from Fallout 3. It was right after the purifier was taken over by the enclave. I had just helped Madison Li and her science team reach the citadel. The memory itself was when we (Me & Madison's team) were trying to get in. Hence, these words:

"Lyons! I know you're in there, I know you can here me! You open up this goddamn door right now!"

Madison Li - Audio

And open sesasme! The gate opens! I'll never forget that.

Mine would have to be leaving Vault 101 in Fallout 3. Just looking around and realizing I could go anywhere. A close second would have to be when I first encountered a deathclaw that was for some reason outside of megaton fighting the traveling merchant. It then shot off into the sky and for the longest time I thought there was some random encounter dragon deathclaw and feared wandering outside of settlements.
