@AlexMarra: Numero dos. People will get their credit from their names popping up on the Top Editors list on the left-hand side. And with the amount some pages change over time, the Mass Effect 2 page for example, the original article and what it might come to be will probably have little resemblance to each other so the original author is largely irrelevant. Plus, articles are meant to be about the specific game/concept/character/whatever, not about who wrote them. Mentioning the creators of whatever property you might be writing about both works as a good launching pad and gives them their just desserts.
