Dave Hopman introduced to me a game called Erie. You can play the game for free from Desura. The creators are currently trying to get enough funding to make a full version of this game. Various people have played it and sent them their comments in a video seen (along with more information) here [url]

The following link will send you to the page where you can play what they do have for free.

Now I do not have desura so I can't try it, nor am I able to give financial support to the creators of Erie, that shouldn't stop any one of you trying it and supporting it. Just from the short video and reading on the game, it sounds as scary/fun to play as Amnesia!
As you can guess, I'm not one of Erie's creators.
