Re: My Email from John Carmack
The engine is friggin amazing. On a pure technical side, it is superior in many ways to Unreal Engine 3. However, the tools that ship with it are rather limited, and do not allow exposure of the ENGINE (not the game) 's true ability.
The reason Doom3 the game isn't as amazing visually as the Unreal Engine 3 based game scheduled for release by Epic in 2006, is because, our hardware cannot cope with the absurd amount of texture maps, shader functions, and polygon counts.
Let me assure you, given the same target hardware as Epic's next game is targetted for, Doom3 could produce scenes as good, or better in quality.
Please separate the ENGINE from the GAME.
