I can understand the reasoning behind Microsoft's decision, and somewhat agree, but ultimately I think something is lost when developers are kept from leaving their mark on projects they spend a lot of time working with.
Not with hookers and blow, but with their names prominently attacked to and marketed with the games. Especially Atari 2600 games.
If you saw a game by Joy McStickerson, you knew it was going to be a quality game, and often would buy it without bothering to read the reviews.
Didn't cut down on the Easter eggs, though.
