One of the latest games by John Carmack of ID Software, also of Armadillo Aerospace contender for the X-Prize cup.

I finished ten minutes ago, and my blood pressure is still making my eyes bulge. Lots of blood and guts and violence and evil creatures that look, sound, and act like they came straight from hell. If you have a heart condition, you won't survive this game (I mean it, don't play!). If you are even mildly religious, you will want to hold a convention of the world's religious leaders to combat this thing from Id ....

Criticisms... it was too long. I almost didn't make the video rental return date. The purchase due date that is. Also, I'm thinking of putting in for some vacation time, just because this game is so traumatizing! Or maybe I'll get a few tranquilizers from the hospital emergency room. Whatever works.
