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.
Creator Backlash: ProtonJon did genuinely enjoy playing ROM hacks of Super Mario World sent in by his viewers, but he eventually got sick of them as more of the ROM hacks contained poor level designs and gimmicks. This is especially shown in Protonjon's LP of Super Mario TKO, where he expects a lot of nonsense he encountered before in other hacks and is not used to TKO having level designs that almost mirrors the quality found in official Mario games. Combined with the fact that ProtonJon wanted to LP other games, he dropped ROM hacks entirely except for one that was sent in to him by a person who wanted someone to LP it since he was dying of cancer. note Except the person was totally lying about having cancer, as ProtonJon later discovered.
Protonjon also got so angry and frustrated with people that sent him ROM hacks that abuse invisible blocks that he created an entire level made out of nothing BUT the invisible coin blocks. The level forces the player to reveal each and every hidden block to build platforms to the top, and they also have to use a springboard to reach the higher blocks. The player must then get the switch at the top and use it at the very bottom of the level to get access to the exit.
Dude, Not Funny!: Jon's reaction to the person who lied about leukemia in order to get him and other people to LP his ROM hack. Jon's reaction was more disappointment rather than angry, but he still expressed that what the person did was not cool at all.
When one of Jon's cohosts on Skype, Gex, had a Freudian Slip that made him blurt out the N-word accidentally, Lucahjin's attempts to make him feel better involved racist jokes that in and of itself left several viewers feeling very uncomfortable and offended, and even lost him a few subscribers.
Ear Worm: The muzak Jon uses to accompany his fortune cookie / straw poll and Intermission cards in his livestreams.
Ensemble Dark Horse: Laura from the Mario Kart Wii videos is becoming very popular with viewers; a lot of people really like the sound of her voice.
Some people from Jon's streams, such as DanTheEnigma, are well-liked in the chat due to gaming skill (or lack thereof) and frequently join Jon in games and calls.
From his Bomberman Act Zero: Dan (See above), Jewker, A Girlbreast, and Draw. The last of these is worth mention, as Draw isn't a physical player, but the actual condition of everyone else losing, resulting in a tie.
"Funny Aneurysm" Moment: In episode 2 of his LP of Notte Luminosa, he finds a minigame corner with a hilarious disclaimer. The disclaimer states that the minigame corner can not be held responsible for side effects such as alcoholism, crossdressing, gender confusion, and... cancer. Why is Jon playing the game? To fulfill the dying wish of the game's creator, who has cancer.
Hilarious in Hindsight: It turned out that the creator was faking his cancer, making this joke a little more lighthearted.
Growing the Beard: Jon has gone through the trope at least twice in his LP career. In the beginning, Jon did lets plays of Nintendo Hard games by adding his own snark and witty commentary. It wasn't until Jon started to do lets plays of various Super Mario World ROM hacks (including Kaizo Mario) that his popularity soared while many memes from Jon were born. After getting tired of doing nothing but ROM hacks, Jon quit them altogether and focused on playing games he likes while giving the viewers an educational background behind the games.
New Super Luigi U gives players a scant 100 seconds for every level, making Jon's infamous quote a lot more applicable.
Combined with Heartwarming In Hindsight, kind of: Jon's astonished joy in the first Bomberman Act Zero stream when after some minutes prodding his chat for volunteers, 'actually managed to get a full room' of 8 people to play the notoriously unpopular game. A few weeks later, he had popularised the game on Twitch to the point that any game room he starts fills up in a second or two.
He uses the 'tada!' sound effect from Windows 95 in his Resident Evil 5 collab for things such as his epic rescue of Super Jeenius ("FOOOOOOTBAAAAALLL!") and when the two of them don't forget or miss anything in a level that he would have to recap later.
Also, his laughter is pretty nice to listen to.
In his livestreams, he uses a clip of Albert Wesker irately saying "YOU WILL GIVE ME AN EGG!" and injects it randomly into the stream at the request of the chat commentators, especially when he gets a new subscriber.
"DEATH WATER" and "NOW I'LL SHOW YOU" are a bit more deserving of their status; even though they each appeared in just one video, Jon repeated them over and over again.
He even lampooned "DEATH WATER" himself with "CHERRY KOOL-AID".
His Super Mario TKO LP, where he encouraged his viewers to play along, record, and upload their own videos. This resulted in a surge of terrible LP videos, and was probably the key factor in the decision to Retsupurae him — note that their primary criticism is his Follow the Leader status.
He actually commented on the Retsupurae video, seeming to take it all in good taste.
Slowbeef seems determined to make the Notte Luminosa incident one of these; though he was very sympathetic about it on the Retsupurae podcast, he's still cracking jokes every time he thinks of it in the videos Jon guests in.
"... but it's still anyones game!" seems to be turning into one for him.
So Bad, It's Good: This is his opinion of Superman 64, in the sense that the game is so poorly designed and programmed that it actually becomes fun to discover different ways to break it.
He also considers Bomberman Act Zero pretty fun if you can get people to play it with you online.
Stop Helping Me!: "Carmen Sandiego", aka Helper #3 in the Deal Or No Deal LP. Protonjon and Kelekin continually poke fun at 'her' dumb advice.
"You can't go lower, Carmen, You CAN'T GO LOWER!!" "You are useless, Carmen!"
