I enjoyed call of cthulhu a lot. It was only programmed by 1 guy so it has some issues. It is a good conversion of the pen and paper campaign escape from innsmouth.
I played the first hours of condemned but wasnt too happy with it because it is more a simple ego shooter than horror.

I can highly recommend to those who liked amnesia to play penumbra 1&2 (requiem [part 3] is more a series of puzzles than a game). Penumbra is btw the predecessor of amnesia.
