It looks awesome.
I wouldn't call it the "most terrifying" though.
The lighting is exceptional, and there's a new height in realism. It rocks.
I thought Half-Life (the first incarnation) and Realms of the Haunting were scarier/creepier. Diablo still has the best most original game music ever.
FYI I don't play, I'm an avid observer, hubby is the game addict. He's cussing at this one, it's difficult apparently.

The Half-Life stabby asparagus things in 'Blast Pit' were severely annoying. Until one realizes that noise attracts them.

I installed Doom 3 and played it over the weekend and it's fantastic. I kinda enjoy the chainsaw. Later in the game the weaker zombies just walk right into your chain saw and it makes the most blood splattering noise and sight one could imagine.

I have a glitch with the game that maybe someone can shed some light on. When I have "Display weapon model" turned on, firing the shotgun locks the game *hard*. The power button is the only recovery. So far, I've been able to get this to repeat with the shotgun and the rocket launcher. Both of them, when their model is displayed on screen locks the game instantly and repeatedly.

If anyone knows of a patch, please freepmail.
