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: Mario Strikers
Crowning Moment Of Awesome: In Super Mario Strikers, any time you pull off a Super Strike, and even more so if you make it a "perfect" super strike. The awesomeness is doubled in Mario Strikers Charged, where the Mega Strike animations are far more epic.
Crystal Canyon is especially good, for only being able to hear it between goals and power-ups.
Even Better Sequel: Charged. It adds a great deal of depth over the original by adding the "charge" mechanic to the ball, giving the sidekicks their own abilities, giving the captains special items, and making the stages have unique obstacles.
Nightmare Fuel: When characters get knocked into the electric fence, they let out cartoony yelps of pain. When the character in question is Peach, however, the scream sounds startlingly realistic.
In Crystal Canyon, the characters are rather violently incinerated by the focused solar rays. They all reappear at the start of each round, but it's pretty disturbing.
Nightmare Retardant: The super team in the original game is a group of black and red menacing looking robots designed by Bowser to beat your team, no holds barred... And then they start doing back flips and dance the Robot.
Oh Crap: When the screen fades slightly on Wastelands, get away from the ball. After a brief moment the ball will be struck by lightning, increasing its charge and electrocuting any players within the vicinity (even goalies).
