Eurogamer and Edge are reliably good. Polygon is very new but excellent. TIGSource covers just about any indie game that gets released, although it's better as a source of information about what's out there than as a reliable review site — the indie community is pretty small, and the reviewers are often friends with the developers. Rock, Paper, Shotgun has some of the best coverage of anything that runs on a computer, including independent games, but it doesn't cover consoles. Venus Patrol focuses on a more artsy niche, although its coverage can be pretty spotty and it's quite new too.

Hope that helps!

Give Giant Bomb a look. They're not quite the same as other sites but I've come to rely on them for getting a pretty even look at the way things are being built, and their video content is top-notch - genuinely entertaining and they tend to have various industry folks stop by for real conversations.
