S.T.A.L.K.E.R., definitely.
There's something to be said about a game with this amount of atmosphere, where even going outside at night becomes something of an issue with willpower. When you're hanging around in the Rookie camp, about to go complete a mission, and suddenly you hear a bloodcurdling howl coming from the distance. That's usually when I think to myself 'do I -really- want to leave this camp?'
Also, any time the game requires me to enter a dark tunnel/sewer. Paralyzed by indecision.
