Alright I'm going to say something that barely on this list, Dark Souls. CeriseArt, what? You heard me. The whole game hypes you up to get ready to kill a God. The one man who is responsible for your trials and every undead before you, and every undead after you. So right as you are about to enter the boss fight, the final fight, THE END ALL OR BE ALL. You are met with no cutscene, no heavy metal lets do this music, no god. You are just thrown into a fight with a man who went from God to husk, a shell of his former self since he sacrificed EVERYTHING to keep the fires linked. His family, his kingdom, his humanity. You are also met with sad piano music, that makes it so you begin to pity him... You find yourself not killing Gwyn out of spite or sweet sweet vengeance for making you die over an over to get to him, you find yourself killing him out of pity, to put himself out of his misery, just as you succumbed to the world over and over, so did he, and he got the worst of it.
