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.
Harsher in Hindsight: One of Northernlion's main complaints about Virtual Bart is that the game's attempt at humor uses a lot of Black Comedy and mean-spirited jokes, such as a game over cutscene of Bart being drawn and quartered, compared to the show's family-friendly comedy. Among the major criticisms of later seasons of The Simpsons is that the humor has gotten too dark and mean-spirited.
Hilarious in Hindsight: In the Virtual Bart Let's Play, he decides to try beating the dinosaur stage by running past all obstacles, and proceeds to discuss a hypothetical idea for a game where it's beneficial to run past all your enemies even though they're trying to kill you...which is a fairly accurate description of Iji.
In one of the Binding of Isaac episodes, he kills an enemy hoping it'll drop something useful, and when it turns out to be useless to him, he says "You might as well give me a lump of coal!" Guess what item was later added to the game?
Most Wonderful Sound: Northernlion's voice, which is one reason why he's so popular.
Squick: A few of Northernlion's comments can be a bit... gross.
