Poor 1up. Those guys can't win for anything.
IGN has been a disaster for a while. They market to a weird segment of gamers and definitely hit the lowest common denominator thing super hard. Also, their articles are not always well written. Not from a subjective "I don't agree with their review" thing, but in a "this article does not have any consistent flow" and "some major editing needed to be done to this preview" sort of way.
All that said, Murdoch wanting to sell off IGN probably has nothing to do with any of that. It's just that video game reporting sites are sort of losers. Since you can't do any sort of actual investigative work or "hard" journalism or whatever so much of your content is out of their hands. They are at the mercy of publishers. If a website wanted to do things without help from publishers they would end up way behind on everything. They couldn't get previews or early review copies. They wouldn't have access to developers or be able to get help from PR people on any sort of issues.
On top of that the way people consume info is different and some of the major gaming sites might just be a bit too big. If most of your content is just previews and reviews maybe you don't need so many staffers and so much money. You're just publishing videos the publishers sent you anyway.
So it's never really surprising when these sites go down a bit.
