I think by Doom3 id had reached a point where they needed a team of programmers, rather than Carmack + programmers orbiting Carmack. And so Doom3 represents their transition to dealing with all the software engineering / communication issues all of us on teams always have to deal with. I don't have any knowledge of idTech5, although I would guess it goes further down the lineage of Doom3. id still has to find solutions to the problem of programmers working on teams, after all - no amount of Carmack genius is going to magically fix that all too banal (and inevitable) organizational challenge. I had my fill of the industry by the mid-2000s and have been working on indie/experimental/violent educational games since, so that's roughly where my big iron engine knowledge fades...
