John Carmack Beyond3D's
John Carmack Q&A is not an actual interview with the id lead programmer,
but it does collect email responses they've received and found in forum
posts relating to DOOM 3, hardware requirements, tweaking, and more.
Okay, so "lead technology" automagically means "graphics programmer"? What about sound, physics, networking... Aren't these parts "technologies" as well? You know, getting a photo-realistic scenery will come a lot sooner than truly realistic physics.
