Good
Insert Credit - Great site covering more obscure games news.
Eurogamer - The best European games site out there.
UK Resistance - Irreverant and hilarious videogame comedy site.
Bad
Edge Online - Boring magazine which takes videogames too seriously.
The Gamers Quarter - Boring online "magazine" which takes videogames too seriously.
Gamestoaster - Bafflingly arrogant and unimaginably terrible Irish games site.
Whatever
GameFAQs - The IMDB of videogames. Best resource for game guides online, just steer clear of the forums.
The Magicbox - One of the best news sources on the net. Too many pop-ups though.
IGN - Gigantic, advertisement filled hell-hole. Lots of content though.
