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.
Awesome Music: Just about every song in the first game. Second Game's Recycling plant (reused as credit music), and Final Boss music.
The whole soundtrack for both games really. Of special mention from the second game is Mist Chances.
