Voodoo Extreme -- During the development of Quake III Arena, you released Q3Test. Are you planning on doing something similiar with DOOM 3? If so, when would you plan on doing it (rather, how far along in the development process, not a specific date or time frame)?The topics in this interview seem to be more focussed on the gameplay aspects of the new Doom game instead of all that technical stuff I don't understand anyway, plus some stuff like possible side projects and Carmack's view on software patents.
John Carmack -- There will certainly be a test. I am a firm believer in the benefits to the final product of doing that.
Q3Test was released too far ahead of the commercial product. The game engine was nearly ready to ship, but the bot code was still completely unresolved, and wound up causing the real ship date to be much later than expected. We will probably try to have a test for the next product much closer to full beta time.
Don't hold your breath.
