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.
Accidental Innuendo: Frequently, which is especially funny because he has many very young fans who would never even notice - if he didn't stop to dwell on the innuendo he'd just made every single time.
At one point, he claimed that he makes too many innuendos in general, especially in Real Life, and would start trying to cut back - but he was back at it again in the very next video.
Awesome Music: 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.
In the original, he calls Goombario useless even though he's not nor does he ever state why he thinks he's useless although this could just be Hate Dumb on his part.
As for the rest of the party members, his descriptions for them are rather mediocre. In TTYD, Goombella suffers the same treatment as Goombario and 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). His party member descriptions are a little better this time though.
In Super Paper Mario, he has a tendency to do things the long way such as working his way up to one of the Securimeows in Fort Francis and enter 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 Merluvee, 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. There are some other minor moments, but the overall research (or lack thereof) he did for his Paper Mario LPs contrasts sharply with the rest of his LPs where Chugga's research was on the nose and if any mistakes were made, he'd usually catch them and put some text on the screen pointing it out.
As of recent, he claimed that Kid Icarus: Uprising was written by the Saturday Night Live staff and those who did the Onion. Masahiro Sakurai, the sole writer for that game, wasn't ever even part of those staffs.
Discredited Meme: 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:
A very large and vocal portion of his fanbase is made up of preadolescent boys, who can be just as annoying as you might expect. They even have a collective Catch Phrase of their own, which many people quote when they want to mock his fandom: "CHUGGA!" Yes, that's it. They just shout his name all the time.
True to form, he lampshaded this by referring to his audience as a bunch of six-year-olds.
He also got agitated by his fans during Majora's Mask at all the complaints about his video length being fifteen minutes when, as a YouTube partner, he can go up to several hours.
If you say that you're not enjoying a current project (even if you only think it's a tiny bit worse than his usual standard), you clearly hate Chugga and want to ruin everyone's fun, according to comments.
ProtonJon has commented that Chugga's fans have sent him death threats over their apparent rivalry in The Runaway Guys. Diabetus received similar threats just for knocking Chugga out of the Super Smash Bros. Brawl tournament. Nothing Chugga says seems to stop them from doing this.
Most of his "fans" actively insult Emile's decision to have a consistent schedule for updates. Worse still, there are "fans" that actively DEMAND him to make L Ps of highly hyped games that came out within hours of their release.
Fan-Preferred Couple: Some of his fans think he and female LPer MasaeAnela would be adorable together. They even call her a female version of him.
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.
Hate Dumb: Almost every single one of his videos has at least one troll saying that the games he's playing suck because of their graphics, and that he should play Call of Duty because it's "realistic." Despite the obvious trolling (especially when you consider some of the usernames of the trolls), people keep responding to them.
Not to mention the jerkish trolls who give Chuggaa grief for being a brony.
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".
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:
Emile: How I wish I recorded my little girl scream from the reveal of EarthBound Wii U coming to the US.
I Super Mario 64 DS, Chugga talks about how maybe at E3 2013 there would be a multiplayer 3D Mario Game. He was right.
A few moments with Jim in Majora's Mask. Later parodied with Francis of Super Paper Mario, where he (jokingly) chooses the options to have Mario call him irresistible and a stallion.
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 some of his earlier LP's he couldn't even go past ten minutes due to the Youtube limit 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.
Another example would be Flareon, whom he dismisses as the worst of the Eeveelutions, going out of his way to bash it whenever he can.
Goombario and Goombella as noted in Critical Research Failure.
After his first Pikmin LP, he dreads Steve. And regarding the enemies, he hates quite a number of them, namely, Wollywogs, Gatling Groinks, Bumbling Snitchbugs, Swooping Snitchbugs, the Water Wraith, Burrowing Snagrets. Also during his first Pikmin LP, he doesn't like the Yellow Pikmin. He changes his mind in the second game though.
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.
