#13 – Eternal Darkness
This GameCube cult classic gave me my first taste of real fear and confusion within a game. Breaking the fourth wall is a very risky endeavor, one that could pluck the gamer right out of their immersive state, ruining the intended effect, but Eternal Darkness handled it perfectly. Silicon Knights kept players on their toes throughout the whole experience, and a sequel with better graphics and a new set of tricks, they could really blow the lid off of survival horror titles.
