I loved the Penumbra games simply for the fact that they scared the HECK out of me. After playing so many gruesome and supposedly horrifying games, you get a little "numb" to disgusting beasts and flying body parts. These games are remarkable in that they create an atmosphere of total horror and desolation out of seemingly nothing. I've never felt so desparately ALONE in a game as with this series. In fact, there's so little there that the first time you actually do encounter another living (I use that term loosely, and you'll know why after you play the games) thing, you'll need a change in undergarments... Totally worth the $5.
