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.
Nick has a hard enough time convincing people that he spoke to the legendary "Ancient Wu," he's not even going to try to explain the insanity of fighting a dragon surrounded by lava in an underground maze.
If you play through the game for the first time only to get to the bad ending, suddenly having the explanation as to why a bunch of goons with automatic weapons are shooting up a high-rise ala Die Hard jump on a desk and shout GENERAL HAN-YU-KIM OF THE NORTH KOREAN ARMY then throw knives at you feels pretty damn random.
