Amnesia: The Dark Descent (Frictional Games, PC) [$19.95]
You have no weapons. Darkness slowly drives you insane and you have limited amounts of lamp oil. Fleeing from monsters means sitting in darkness, slowly losing all your senses, and hoping nothing catches you in this state. The experience stayed consistently disturbing throughout the game as the challenges grew more complex. The mod tools have recently gone online, meaning there will be a lot of strange content for owners to enjoy after they’ve beaten the game. It’s a great gift for anyone looking for a few chills this Christmas.
