I downloaded the Left 4 Dead demo through Steam today, and I am very impressed. Not blown away, but definitely impressed. The demo only allows you to play the first to parts of one of the "movies", so i played it a couple of times on single player campaign mode, and it was hella fun. The AI Director works wonderfully, each time I played it was like a new experience. I am going to play it a lot more over the next couple of days, and buy it as soon as I have some spare cash.

My computer has some problems with it. I can only run it smoothly at low resolution, but even then it doesn't look horrible, mind you that is my laptop, so I may tear open my desktop and see what I can do with it. It may make the difference between impressed and blown away if I can get it to run with a higher resolution.

I have to get some people together to play the co-op mode as soon as possible, like...now...I want it to be people I know, and I have to get my microphone working.

Nice! The commercial for Left 4 Dead just came on Spike TV, which I believe can only be a sign from god that I must own this game.
