Actually Amnesia is the kind of game I could play because I know that regardless of how scary it gets, it is only a mood, nothing will happen, ever. The enemies that do appear usually do so from quite far away so it is very easy to avoid them. I tried playing the FEAR demo, but I didn't get very far before I just ended up ruining the gameplay by closing my eyes on the scary parts, looking into walls, pausing, etc.
Edit: Watched all of them now, should be about time for some different enemies now imo. The regular soldiers appears to do plenty of damage, but they go down fairly quickly and honestly I have seen too many soldiers over the years for them to be interesting enemies The mini boss was a nice change, but that didn't last too long sadly.
