Talk about self serving. Not getting credit hurts integrity? How about gaining integrity in ways that matter to gamers! Like stop giving glowing reviews to games published by advertisers. Like asking tough questions when you talk to publishers/developers instead of sounding like you have a cup in your hand: "Please sir, may I have somemore."
Game journalist behave like game publishers can crush them. Game journalists need to behave like THEY can make or break games. Even if it is not true, that should be their approach.
