I recently played a game called "Dark Fall: The Journal". It's a simple point/click game by The Adventure Company. There's an interesting story to it, and some nice touch of atmosphere that at times make you a little uneasy- especially when you're playing with all the lights out, the surround sound turned on, and alone.

When you install the game, it also installs a link to their home page, where they have links to a few ghost cam sites.

They're currently working on "Dark Fall II", which I'm looking forward to playing when it comes out.
