I had seen the demos and reviews of Amnesia, so I knew it was great. But I just bought a copy yesterday, and it really is something else. It's a casual game, but it's got style... Unlike other casual games, like UNO for XBLA.

I'd agree with you that it's terrifying, too. This is the first time I've felt that way about a game. The whole experience is like watching Alien for the first time.
