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: Super Princess Peach
Game Breaker: Practically every upgrade is one of these. Each one makes it more and more difficult to die.
It's Easy, So It Sucks: Compared to other Mario games, SPP is rather easy to finish... right up until you get to Bowser.
Unfortunate Implications: Critics jumped upon Peach's use of abilities revolving around rapid, violent mood swings.
This is lampshaded in X-Play, where Morgan remarks that the only thing "Super" about Super Princess Peach is that she's "super emotional".
