These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
At the ends of his Majora's Mask videos, he features a ZREO remix of a song from the game relevant to the events of the episode. And, in general, he tends to pick pretty good music whenever he needs to speed up footage or make a montage, often using rock covers of video game music by CarboHydroM and CSGuitar89.
He also points out game music he considers to be examples of this trope.
He considers the music in Jolly Roger Bay from Super Mario 64 as one of the best songs he has ever heard.
Broken Base: Fan response to his Sonic Colors was rather mixed, which he mentioned in one of the last episodes of that LP. Complaints ranged from how Chuggaaconroy is wasting time on a non-Nintendo game, Chuggaa's lack of skill regarding the game, to Chuggaa choosing to do Colors when there are far superior Sonic games out there.
Creepy Awesome: His profile icon during Majora's Mask, and his one for Pokémon Emerald to a lesser extent.
In Paper Mario: The Thousand-Year Door, he states that the player can go back and fight in the Glitz Pit after completing Chapter 6, when in reality, the player can go back before starting chapter 4 (the player does have to return to Rogueport first).
In Super Paper Mario, he worked his way up to one of the Securimeows in Fort Francis and entered the wrong passcode to be sent to the dungeon where Carrie is imprisoned stating "that's how Nintendo intended for you to do it", even though if you were to check with Merluvlee, she tells you to flip into 3D and walk behind the first door after the entrance (without opening it) to access a warp pipe that will take you to the basement and allow you to recruit Carrie all the same, in less time.
Steve the Trooper. Chugga hasn't named any Pikmin Steve in his Pikmin 2 LP, and heavily implies that he is tired of all the fan attention the throwaway gag got. Though he indirectly made jokes about him during the LP, even in the finale. This trope is officially Zig Zagged. Chugga now acknowledges Steve exists, but he has a spirited reaction when someone other than himself (usually ProtonJon) brings it up. He ends up bringing the meme up again in his Pokemon Emerald LP when he ends up fighting PokéManiac Steve, especially after this exchange:
Steve the red Leaf Pikmin for being a trooper once had a Facebook page. In the finale of Pikmin 2, after going the entire game trying to mention him as little as possible, he gives in and lets him have the honor of carrying the lightweight and final treasure in the game.
Slavinator (his Zigzagoon HM Slave) is the fan favorite of his Emerald team for similar reasons as Steve, but not to the same extent. Fans must've learned how Chugga takes things like that.
His Pokémon Colosseum LP gave us Affection the Misdreavus. Part of the reason for her nickname was to acknowledge how popular she was.
Marshall the Quagsire, for the spectacular last battle against Evice.
Roary and Darmani (his Arcanine and Donphan in Crystal) considering how difficult it was for him to capture them. Along with Methane, his shiny Wheezing.
Chugga visited her town in his Animal Crossing: New Leaf LP. The commenters went crazy...again. It even got to the point that when Chuggaa said he had a very special announcement ( which turned out to be that Amelia was living in Masae's town), many people thought it was gonna be that they were together.
In Part 48 of the PokémonFireRed LP, Chugga joked how trainers and their monsters should just die to save him the annoyance of dealing with them. Two seconds later, he bumped into a guy mourning his Onix. He lampshades his horrible timing.
He also stated that he had no plans to LP Super Mario 64. Technically true; his Super Mario 64 DS playthrough began on April 23, 2013.
Also, in 2009, Chugga comments in a video of his SMS game "...I'm surpised PETA hasn't gotten on this game, yet." Another Mario game would become a target of PETA later, being one of the targets they make a mock game for meant to show the animal cruelty the game is "promoting".
His first use of the now-famous name is when he says "We'll just call him Steve and we're not going to like him." Let's just say the "not liking him" part would turn out to be an understatement.
In his Special Features video for MOTHER 3, Chugga announced that EarthBound would never be re-released outside of Japan. 4 years later, Nintendo announced they would do just that. Chugga's response on his Twitter:
"How I wish I recorded my little girl scream from the reveal of EarthBound Wii U coming to the US."
In Super Mario 64 DS, Chugga talks about how maybe at E3 2013 there would be a multiplayer 3D Mario Game. He was right.
Chugga talking about how changing someone's name while their knocked out as a joke becomes really funny after the same thing happens to him in Dokapon Kingdom Episode 3.
Parodied with Francis of Super Paper Mario, where he (jokingly) chooses the options to have Mario call him irresistible and a stallion.
Humor Dissonance: His puns, especially those involving the names of characters in Pokémon Colosseum. Are they incredibly witty considering how quickly he comes up with them, or is he trying too hard and spoiling the few genuinely good ones that he comes up with?
It's Short, so It Sucks : What some of his fans cry whenever he posts videos that are usually less than twenty minutes long. He calls them out on it when he points out that for his earlier LPs he couldn't even go past ten minutes due to YouTube's restriction at the time, so they should be happy that he can post longer videos now.
His Zigzagoon in Pokémon Emerald (who is named Slavinator) is slowly becoming one, by staring down at Brawley's Makuhita while ACOOLTENT (Chugga's Tentacool) chipped away the last of its HP via poison sting. It gained four levels just by staring at him.
Steve The Red Pikmin. Regretted and sometimes lampshaded by Chugga. Chugga lampshaded this with Bulby the Bulbmin.
The "No coin left behind movement", much like Steve, Chugga regrets saying it and thinks his fans are absolutely insane for actually doing it.
If you see someone doing the Russian dance in a similar manner to the Redeads in Ikana Castle and someone else starts singing MOSKAU! MOSKAU! I DON'T KNOW THE FRIKIN' WORDS!, you now know why.
LegendaryGerbils was born when Chugga got annoyed at people contesting that the three legendary beasts were always referred to as dogs/cats, mentioning this on a forum is a good source of Internet Backdraft.
There's a picture going around of the time Emile made a funny face during a StephenVlog video.
Narm / Wild Mass Guessing: When he talks about the "theme" of Majora's Mask along the lines of Link getting progressively less small and scared. It's not a bad idea, but it's largely Wild Mass Guessing since there's no real evidence of this, taking a lot of the meaningfulness and emotion out of it since it's really just Chugga's made up theory. It's not helped by the fact that part of the theory relied on Link's personal feelings, none of which are ever displayed and doesn't really contribute much to the game.
Like ProtonJon and "move faster pokey" before him, Chugga has the same negative reaction whenever the name 'Steve' is mentioned near him.
On the giving end, Chugga pulled one on fellow LPerThe Khold One in Pokemon Fire Red: in Khold's LP of the game, he traded a Spearow for a Farfetch'd only to complain about how much the Farfetch'd sucked. Chugga eventually names his Spearow Khold to show him what "he could've had". Considering how awesome the Spearow note later Fearow is, it freaking works.
Trying to make conversation with the moon while he's bored and waiting for aliens to attack the ranch. "...read any good books? Ah, the chapter in the bible on the apocalypse. Ah."
There was also the Tanetane island Mushroom Samba from Mother 3; in the game, it's utterly horrifying. Chugga ruined it by acting like a stoner through the entire thing. This was so bad he actually uploaded a second video with his commentary completely muted to preserve the original atmosphere.
Chugga mentions in Colosseum that most of the time in his Pokemon playthroughs, his last pokemon in his team tend to end up as The Scrappy to most... but in fairness he usually has good reason for each of his choices for all his Pokemon, and his last Pokemon on all his teams have been no exception.
Shari is a humorous example. Chugga is creeped out by Shari's appearance and dismayed by the fact that she's the animal whose emotionally closest to him.
If Youtube comments are any indication, it seems Trifecta the Dodrio is getting this, due to her getting destroyed in nearly every major battle.
An interesting case happens in Okamiden. Manpuku is considered The Scrappy of the game by fans, Chuggaa included; however, Chuggaa also argues for Manpuku's good aspects, like going to save his mom for his actions.
Serious Business: He takes background music very seriously. At one point in Pokemon Emerald, he has called the person in charge of assigning certain songs to certain locations an idiot for having a happy song play outside of a cemetery location. A bit much, given that the location's role as a travel route had priority.
He does tend to (jokingly) insult females a bit too much.
In his Paper Mario LP, he related an anecdote about a lesbian he knew, and stated that "it's totally her choice." What he meant was that he had no problem with her sexual orientation, but some commenters misinterpreted his words and accused him of saying that homosexuality is a choice.
Viewers Are Geniuses: He doesn't hold back the tech lingo or obscure game references. Most of the time it's Okami.
Watch It for the Meme: Some people who've subscribed to him later on went back to watch Pikmin just to see who this Steve person everyone talks about originated from.
The Woobie: Chugga himself. His deleted 50 facts video revealed that he had four siblings that died in miscarriages, he nearly died from an allergic reaction as a kid, and he was bullied in school. He's also admitted that he was only pretending to be enthusiastic in his Super Mario Sunshine LP since he had been worrying about health problems during it.
The video has been reuploaded by another Youtuber and can be watched here.
Iron Woobie / Stoic Woobie: He doesn't talk about it or let it stop him from being the goofy, nerdy gamer we all know and love.
Parodied by lamenting the apparent death of a Koopa in Chapter 2-1 of Super Paper Mario, how the Koopa drowning instead of getting jumped on was the saddest thing ever.
In the finale of Link's Awakening, he rather offhandedly mentions that he suffers from nightmares often.
Being the only gamer in his family isn't bad, except half of his family thinks video games are from the devil despite the fact that his dad does drugs while the other half are casual gamers who otherwise think video games are a waste of time.
