Eh, I'm not very into scary things for games, so... technically, I haven't "played" any of them. Mostly I just sit and watch my friends play the games, and I tend to point out the creepy things that wander up behind them. xD

That said, my favorite game I've "watched" was Silent Hill 2, though to be fair that's the one I know the most about, so... I may well change my opinion once I've "watched" some more of the other games.
