IGN sort of has a problem with reviewing Wii games. According to Alexa, their Ps3 section gets nearly three times as many hits as their Wii section, as does their X360 section.
In fact, the Wii section is only 50% larger than the Ps2 section.
When one section triples the other, it's natural for a site to get some bias towards the larger one. If you want IGN to become more "balanced", you should try to give them hits on their Wii section, rather than to avoid to.
