At a small Chinese restaurant, over dinner, a simple   question was asked of John Carmack. We wondered how he  was able to do such amazing things with his engines [...] He looked up from his dinner and with all due modesty just said:  "Well, I like to think I'm pretty good at what I do."

Ten years, and many engines later, it's no different.  Last night John sent a shockwave through the world of gaming that will be felt for years. We got a peek at Doom 3 - or at least it's engine. Yup, he's pretty damned good as what he does all right :) /applause

Unfortunately, the giant projector screens are not color calibrated the same way at all. The colors did get rather washed out on the big screen.
