Dragon Quest VIII/Nightmare Fuel


 * It's hard not to get chills at the cursed Castle Trodain. Or seeing a giant for that matter.
 * If the player hasn't gotten the Sun Mirror, they'll wander around the Dark Ruins until they hear Dhoulmagus's laugh before being kicked out of the dungeon.
 * Even some of the enemies can be disturbing. A Capsichum, one of the first enemies in the game, is two gigantic, anthropomorphic bell peppers, impaled together on a kebab skewer.
 * The cut-scene where is rather terrifying--particularly the glowing eyes.
 * The game's final dungeon, the Black Citadel has a rather unnerving atmosphere to it due to the later parts of the dungeon (the town section) as well as the dungeon theme.
