The end of his Wii Salute, as well as the end of The Nerd Christmas Carol. The latter got lampshaded by his declaration of only reviewing good games lasting for about four seconds before he counterdeclared "Fuck that, let's do some shitty ones!", complete with holding up a Virtual Boy.
And before that, when the Nerd is taken back to the past, there is actual late 1980s-early 1990s home video footage of him and his sister playing video games (with his father taking out the trash in his underwear); his playing Super Mario Bros. 2 and losing, with his "This isn't fair!"; and his family gathering together for gift-unwrapping, when he got a Super Nintendo console and squealed in glee, "My first 16-bit machine!" Awww.
The short scene with James and Kyle watching and laughing at all the nerd theme song remixes at the end of the The Wizard review intro.
The intro card saying 'Thanks to all the fans!'.
The behind-the-scenes video of the first AVGN vs Nostalgia Critic "Final" Battle are both heartwarming and hilarious. Watching the two actors getting along and laughing together is strangely aww-inducing. Especially when the Nerd sics a kitten on the Critic.
At the end of his four-part review of the Castlevania series, the Nerd notes that "The credits sequence [of Castlevania IV] shows little replays of each level. It's like watching old memories. And that's what the Castlevania games are to me: Memories that will last forever." The credits sequence of the video then does exactly this, showing scenes from all of the various classic Castlevania games, right up to different renditions of Dracula's keep. In the final screen of the video, as we watch Dracula's castle from the original NES Castlevania crumble in the distance, the following words appear: "You played the greatest role in this video. Thank you for watching."
In his Godzilla review, he praises the newer Godzilla games, saying he should have been born later for these games. Even better is that it is rather obvious that it isn't the Nerd speaking, but James himself.
The 100th Episode ends with him hugging all his shitty games, having fought for them beforehand. To top it off, the last shot of the review is that of Simon's Quest, which reminds us where it all began.
To elaborate, ROB tells him that he aims to destroy every bad game, except for Gyromite and Stack Up. The Nerd realizes that all his troubles will be over...but he decides to stop ROB anyway.
On top of this, the memory to suddenly snap him back to life and make him realize he doesn't want the shitty games to be gone is his first ever on-screen appearance when first reviewing Dr. Jekyll and Mr. Hyde, a game he's repeatedly said is among the absolute worst ever made and had driven him to Hyde-esque madness upon reviewing it a second time.
AVGN: You're no hero! THIS IS MY HERO! [Grabs Mario plush]
And a Heartwarming in Hindsight moment: one of the games that he's seen hugging at the end is Ghosts And Goblins, the very first NES game James ever played.
Also, during the Battletoads review, after Kyle Justin tearfully tells The Nerd about how he's been behind the couch the whole time, you see for a split second that AVGN was actually touched before he grudgingly allows Kyle to join in the review.
The entire Swordquest review. It's notably a lot more respectful than many of his other reviews, and the ending really cements it.
A meta one, but for the Angry Video Game Nerd movie, James asked his fans to help contribute a small portion of the budget, $75,000, through here. ...and in less than a month after posting that video, over $100,000 was raised, and rising.
The donations proceeded to exceed even this by a further $75,000, less than a month after James posted a video video thanking donators for their incredible support. To put this into perspective, the total donations have exceeded the original goal by $100,000, and it's possible that the movie may end up being completely fan-funded.
Ultimately, they made over four times the intended goal.
The "Contra Memories" review, where James speaks independently of his "Nerd" character and tells the story of his first time he beat Contra. He talks about how the ending of any game was a lot more special back then due to games in general being harder, not being able to look up the ending on the internet, and not even knowing what the game's villain and/or last bossisexactly. He actually finished the game in the morning before school one day, with his parents watching, and he apparently still tells people "I beat Contra before breakfast!" Seeing James do a nice, positive review praising a game and seeing him fondly look back on his childhood like this is not exactly funny like the other reviews, but definitely adorable and "aww"-inducing.
The Scwarzenegger games review has a genuinely sad moment near the end of the video when you see for a brief second the skeleton of the Guitar Guy behind the Nerd's couch. While sad in itself, if you examine the shot close enough, You'll see that the guitar that he is holding is intact, and is also located behind the Nerd's new futon, both previous ones who were broken during his last appearance. This implies that the Nerd atually went ahead and bought new ones for him before he died.
I see now your greatest weakness is not the hate you have for that game...but the love you have for your fans.
From Ikari Warriors. The Nerd revives the Guitar Guy so he has a second player. He starts out in a pretty bad mood, but it doesn't take long for him and the Nerd to be cracking jokes and just hanging out like best friends. The best part would have to be the Nerd struggling to not crack up when Guitar Guy starts obsessively singing about the 'Scrotum Guns.'
While Lloyd Kaufman is co-hosting an episode The Nerd is visibly happy, and laughing. It seems the whole episode that it is James in The Angry Video Game Nerd costume; he isn't swearing as much as other videos; he is more of a fan of Kaufman and letting him joke about it.
The Nerd screaming with joy when he finds out that LJN made a game that isn't shit: "Spider-Man and Venom: Maximum Carnage".
The effect is lessened once you learn that LJN never made a game inhouse. Instead, they always outsourced their games to different developers. Instead of finally making a decent game, they finally got a decent developer. The moment still counts, however.
"Oh my god... Oh. My. God! They did it. They pulled through! Oh my god! They made a game that's not a steaming pile of fucking shit! OH MY GOD! THEY DID IT! THEY MADE A GAME THAT'S NOT SHIT!"
When the Nerd finally plays Big Rigs: Over the Road Racing, one of the most notoriously bad games of all time...he actually has the time of his life, driving through buildings and up walls, and discovering a new glitch every few seconds. He's dumbfounded at how the game managed to get released, but he actually manages to have a good time with one of the worst games ever made.
The Nerd announces his retirement from making videos, believing his mission to warn the world about shitty games to be a failure due to the fact that the Desert Bus exists, people are playing it, and someone even made an Atari 2600 version of it. The entire episode is heartrending until he then plays a romhack of Simon's Quest that for the most part fixes all of his complaints with the original game, which is enough to lift his spirits and cancel his retirement since he did make a difference after all. It cheers him up so much in fact, that he declares he has to do something bigger than he's ever done before.
