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.
Adaptation Displacement: The actual video game adaption of the Creepypasta (which simulates the experience) is more well-known and seems to be considered superior by quite a few.
Cliché Storm: Many of the tropes found in video game creepypastas are found here played completely (and unashamedly) straight.
In An Ordinary Sonic 1 ROM Hack, you must warp out of the Dark World to beat levels. If you're on it and Sonic.exe isn't chasing you, he'll be where the level goal was supposed to be. He just sits there, laughing and staring. Due to the random, luck-based gameplay, finding him there is both terrifying, hilarious and irritating.
Deader Than Disco: While the original pasta has a large amount of fans (any visit to YouTube or deviantART can prove that), it has also generated a vocal hatedom within the creepypasta community for its poor writing, overuse of cliches, and other Narmy aspects, to the point that the Creepypasta Wiki admins have since moved it to the Trollpasta Wiki.
Small Name, Big Ego: The creator really holds his story in high regard in spite of its limited influence, and threw a conniption fit when he found out that it was taken off of Creepypasta Wiki and moved to Trollpasta Wiki.
Snark Bait: The story has made for some popular riffing material. Memorable takes on it include the following:
It's Popular, Now It Sucks: Ever since it was posted in the Creepypasta Wiki and the fangame adaptation, it has gained wide spread popularity across the net, and since then many find as one of the worst examples of creepypastas out there.
This trope is the reason it was moved from the Creepypasta Wiki to the its sister site, the Trollpasta Wiki (along with many other old creepypastas that fell into this trope). However, a number of users there make it clear that they think that it was never a good story to begin with, which would make this an aversion.
Tear Jerker: Seeing Tails cry in absolute fear as Sonic attacks him.
Values Dissonance: Tom spends the entire story worrying about fictional characters and mourns over their gruesome deaths unlike his real-life friend, who probably died horribly trying to save Tom. Yuriofwind during his reading of the creepypasta puts it best: "Some friend you are!"
Villain Sue: Sonic.EXE can't be damaged by any means and can warp into the real world, turning anyone who he crosses paths with into his slaves. His extended backstory only establishes this to a greater degree.
