Yeah, you've got a few holdouts on the Japanese side, probably largely due to how Japanese company culture tends to work, tho I'm guessing they all still have to compromise with the corporate side of things, unless maybe if you're Miyamoto. But on the Western side? Not so much. Well yes, you've got guys who serve as the face for a developer, for example Hugo Martin for id Software, but I've never gotten the impression that the new Doom games are specifically his vision, or at least in large part his vision, not like the old Doom games were the brainchild of Romero/Carmack.
The only exception I can think of is David Cage, tho that would be a depressing thought, if Cage really was the best the West had to offer in terms of AAA video game auteurs.
