Tear Jerker / Shin Megami Tensei I

• When your mother gets eaten by a demon, who then disguises itself as her, very early into the game.
• After Tokyo's been nuked, you return to it 30 years later after taking shelter in the Diamond Realm...and discover that it's turned into a demon-infested wasteland of lawlessness. Who knew a map could pull off Scenery Gorn?
• In ALL routes, both of your friends' deaths. In Law or Chaos, the one you aligned with is killed off either by an artifact too strong for him, or by the friend you didn't align with. Said cross-aligned friend has to be fought and killed. In the Neutral path, you kill both of them yourself.
• What makes this game sadly tragic is that, unlike the following games, the Neutral route is considered the least optimistic in the series as the protagonist is all alone with only his partner and his admittedly small team of demons under his control against both forces of Law and Chaos including his two friends who immediately want him dead the moment he choose Neutral and berates him for his desire to balance freedom and order in such a broken and divided world. Even more tragic knowing that the protagonist is simply a normal high school boy who was caught up in the conflict compared to the other protagonists who are special in their own way.
