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.
In Final Doom: Evilution, his playthrough of stage 30. The opening of the video basically goes "Let's go die repeatedly to this obnoxious puzzle."

When he started his HardcoreMinecraft, he spawned on a tiny island far from land with only a lone tree and seeds to live off of. He's now gone over 50 parts still strong and now has a Nether Portal, cow farm, miniature castle, village and Enchanting Table. All on his tiny isolated island. Considering how great the odds against his survival were at first, this is a great accomplishment.
