For a game named "Torment", it can be quite funny and lighthearted at times. But when it does get serious, you will quickly realize that the name is very apt indeed.
- The ending(s) of Planescape: Torment are tearjerkers. The best ending is bittersweet. The bad ones are crushingly tragic.
- Deionarra's plight is one of the most Tear Jerking aspects of this game, for those who have any tears to shed. Her haunting theme helps a good bit.
- The "Longing" sensory stone in the Sensate Hall contains a memory that describes, in a most heart-breaking way, how Deionarra perceives the Nameless One. The experience is amplified by his own memory of that event, revealing that the Practical Incarnation didn't actually return Deionarra's love, but was planning on letting her die from the start. You can continue where he left off and ensure that her love remains hopeless.
- When you talk to Deionarra for the last time, you can choose to spin a Practical Incarnation-style lie to get her to help you, and she does. After you are gone she lingers for a little while and says "I forgive what you have done... my Love". She knew all along she was being had.
- Any character back story in that game is liable to crush your soul. Morte being beaten by the Practical Incarnation. Ignus's training. Dak'kon's... everything.
- And their respective scenes in Fortress of Regrets, when it is revealed what happens to those who travel with The Nameless One. Annah's is particularly sad and emotional one. Yes, they all die in his stead so that he may reincarnate, and they become the shadows that h(a)unt him relentlessly. At least, with the best ending, they recover.
- There's a woman who works in the Smoldering Corpse just so she can be near Ignus - which is already a sad thing, since he seems much more in love with flames than with everything else. Then, after freeing him, you can talk to her. Ignus first reaction? He hugs her. And she's just so happy that she lets herself burn. Maybe flames weren't really everything for him.
