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: Soul Sacrifice
Bad Export for You: Some fans weren't exactly happy when it was announced that the Japanese audio was paid DLC.
Complete Monster: Though most Archfiends qualify as Woobie, Destroyer of Worlds, the Leviathan easily hits this trope. He began as the younger twin of a king. Due to being younger, he was often overlooked and shunted to the side for his brother, causing him to grow incredibly jealous and angry. One day, he was given a bird, and angrily tortured it to death. Finding he liked the sensation of power this gave him, he asked for another bird. And another. Soon, he had a variety of animals he routinely tortured to death, his favorite being the crocodile, since he felt strongest torturing something strong. One day, his brother left and he took over, but still felt the desire to kill his brother. The the chalice appeared, and turned him into the Leviathan, who maintains the single minded need to kill his brother. Notably, he's the one of the few Archfiends who never crossed the Despair Event Horizon at some point, merely being angry.
Crowning Music of Awesome: The game features an orchestral soundtrack recorded at Skywalker Studios, and composed by Yasunori Mitsuda (of Chrono Trigger fame) and Wataru Hokoyama. The music we've heard so far seems very promising. See the main menu song.
Fridge Horror: If you save Magusar in the final battle the protagonist begin a cycle of defeating and saving Magusar over an over, while line between the protagonist and Librom becomes blurred and they become one. They fight with Magusar for years until the protagonists body breaks down and can no longer fight. Like the original Librom, they sacrifice their body to become a book that will pass on both their story and Librom's tale to the next prisoner that can take on Magusar. While scary enough on it's own, the cutscene shows SEVERAL books there, making one wonder just how many people have done this...
Player Punch: A divine arm playthrough in itself. Your organization hates you because you're saving monsters instead of eliminating them, as they want, then They send bounty hunters to kill you, and you cannot save them, you need to sacrifice them to keep going. Then you're going to endure joining parties where most players have dark arm, and they'll want to sacrifice the very monsters you intend to save.
Tear Jerker: The Minotaur's backstory. All she ever wanted was a family...
Woolseyism: The Arthurian mythos references have been veiled in the US and EU releases due to some areas of Europe still treating the mythos as Serious Business, hence Nimue's name change to Sortiara and Merlin's to Magusar.
