#10 Amnesia
Any game that offers a character that will eventually go insane cannot be a bad game. Amnesia’s protagonist has a constant conundrum. Being mortally afraid of the dark, being without a light makes him slowly go nuts. But being well illuminated means the game’s monsters will see him. Also, if he looks at the monsters, he will go nuts even faster. So the player will spend any time a monster is close in the dark, losing their mind, staring at the wall, listening intently for the creature to pass by. Which makes Amnesia one of the most intense games in existence.
