They never do something amusing with the credits, so I just ignore them.
I want to design a game with only 10 people, publish it, and make them put "Very short credits" as a selling point on the box.
There's not even a point in having those credits roll in at the end. We paid, they got their money, do we really need to thank them as well? I think not.
Make the list available in case someone wants to use one of your staff someday but they shouldn't make them mandatory.
Damn RPGs with their "Game save +"-files that can only be saved after the unskippable credits =_=
