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.
YMMV: Over The Gun
Accidental Innuendo: Happens in RE 3, Nemesis, after getting away from the huge worm... thing and claiming he did it because of his 'Master Baiting' skills. However, this time, he slips up and it soundsl ike something else... This is, of course, immediately lampshaded by himself as he KNEW it would only be a matter of time before said slip up occurred.
Critical Backlash: Thoroughly enjoyed the reboot of Syndicate, despite the lukewarm reviews its gotten. He never mentioned the original series, though, and judged the game purely on its own as an FPS.
Ear Worm: He's just as easily affected as any of us. Shows out the most in Mega Man 4. Even when he's at the peak of his Rage Quit, you can still hear him grunting Dive Man's theme in frustration. (First set stinger)
Silent Hill 2: While playing the completely awful PC port, Over The Gun ran into numerous glitches. A recurring one was the sound looping in cutscenes glitch. Over The Gun dubbed these glitches "MC Konami's remixes"
Silent Hill 4: Upon encountering the Patient enemies in the hospital for the first time, Over The Gun exclaimed "Is that a woman or a dude?". Eventually they became known as "Woodes".
Splatterhouse: Called "Jason" during the original HTSF, rectified to Rick in the sequel.
Louis from Left 4 Dead, due to his Artificial Stupidity at the Death Toll campaign finale. To the point where Lliam goes out of his way to kill him pre-emptively in the safe house and refuses to rescue him on the way to the last battle. When the bots do eventually rescue him, Lliam begins to gun down Louis and even continues to do so while his entire team is being attacked by a horde.
Ray The Flying Squirrel Yellow Motherfucker, for not knowing what species he is in the beginning and his "shit-eating grin" from SegaSonic The Hedgehog.
Sell Out: Following his decision to not upload HTS Fs to Youtube due to monetization issues.
So Cool It's Awesome: As noted below, he regards most games he plays through as this. In particular though, he has recently stated that Metal Gear Solid 4 was his favorite game, after completing the HTSF of it.
And now, shortly after starting a second run of Chrono Trigger, he's announced that it won't be finished either.
Tough Act to Follow: Since he was the first person to upload Still Alive on Youtube, needless to say his other videos will probably be doomed to being his less viewed videos.
Values Dissonance: In HTSF @ Syndicate (2012) E1P2, he notes how mechanics which were considered cheats and illegal hacks in First-Person Shooter games years ago are now considered features or even standards in recent days.
