I visit exclusively for the forums. I occasionally look at news articles (occasionally I'll skim through a review of a game I'm interested in and I like reading interviews and such), but for the most part the main site doesn't hold much interest for me. The forums are top-notch, though; well-moderated, and full of interesting (and intelligent) folks. One of the few decent ones I've ever found, especially pertaining to gaming. And it's maintained this quality since the early days of PGC.
But I rely on the opinions of people I know (offline and online) and my own intuition for game purchases. I never trust reviewers, no matter who they are or what site they represent. I think reviewing (be it movie, game, or whatever) is fundamentally flawed, and hate it. So I'll use NWR for news snippets, mostly, and interviews. All of my media I get via IGN, but that's all I use them for.
