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.

In the anniversary release of Four Swords, one of the levels for the Realm of Memories that the Links could play in is a level based on the first Zelda, down to the graphics.
