Well? The four sites I've used the most in the past:
Kotaku — I hated Kotaku for a long time because they couldn't shut their stupid mouths regarding vapid social issues in every other post in a pathetic attempt to look profound and progressive, but they've got better recently. It's not just videogame coverage, and none of the coverage is deep or smart or anything, but it is broad: anime, miniatures, board games, rpgs, japan, technology — if you wanted to look at any of these topics more seriously, any dedicated site would be better, but for a casual selection of nerd culture tidbits I don't mind Kotaku too much.
Rock Paper Shotgun — their main problem by far is their writing, which is so forced eg. forcing "humour" and "commentary" into every post, which see them falling flat on their stupid faces nine times out of ten. Like, it can genuinely be cringe-worthy to read sometimes, watching these talentless hacks half heartedly following company policy to add "personality" to every post. Even when it's just pointing out a new trailer they have to manufacture some awful schitck — we just want to see the trailer you idiots! Making a pun then talking about how bad the pun for three paragraphs doesn't add value to your posts! Christ! On the upside, I do find out about some interesting games from these guys.
Polygon — nice graphic design. News coverage is not comprehensive and they don't even seem to pick the best stories. Probably a combination of layout, story choice, title choices and reporting style, but I'll scan their news page and nothing really excites me. Kind of a boring site.
All Games Beta — best videogame news site on the internet? Zero bullshit, just screenshots, videos and developer comments, in a perfect, straightforward, clean layout with the focus on the games, all recent content on the same page one story after another, no ads. No commentary (either professional or in comments sections), which means no idiocy but also no insights, but seeing as idiocy rules everywhere and it's bad commentary which makes so many other sites intolerable, I'll happily lose the potential for good if the bad is non-existent. I wish other sites could learn something from this one (and then kill themselves).
