I always saw them as kind of the Colbert Report of video game websites. Spoofing slated things like Fox News to the point where it's obviously a joke.
I mean, their reviews are pretty much always 10/10 for Playstation titles, while just look at how they reported the last NPD figures:
"The Sony Family showed very strong July sales with a total of 595,000 pieces of hardware sold. In comparison only 170,000 Xbox 360s were sold and the Sony platform even managed to outsell the much hyped Nintendo Wii which only reached a total of 425,000 sold. Here is the complete breakdown of U.S. game sales in July:
PlayStation Platforms 595k
Wii 425 k
Nintendo DS 405 k
Xbox 360 170k
Game Boy Advance 87k"
They tend to be very anti-Microsoft in their reporting, and rarely pick on Nintendo in contrast though, for whatever reason.
