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.

Magnum Opus Dissonance: Egoraptor claims that his best work is Sequelitis, due to both the time and effort he put into the episodes and the fact that he values an ability to make people think over an ability to make people laugh.

Shallow Parody: While most of the videos are Affectionate Parodies of the games they're making fun of, Awesome Reach falls into this, being more of a Take That against fans of the game than it is a parody of the game itself. In fact, it doesn't even make fun of the campaign or multiplayer gameplay at all, but just makes jokes about fans treating the game like a drug or getting erections from playing it. Egoraptor even says in his video description that he hasn't played the game.
