Actually despite the OP stating that Yahtzee is a ranter but he's currently the only single reviewing source I trust nowadays, except for general opinions on forums and stuff. There is one simple reason for that. He will, with a hundred percent certainty, list everything (or nearly everything) that is wrong with the game, and that's the only thing that interests me. I don't care about how the Gamespot dude thinks the game is the second coming because of *insert boring and overused feature*.
There was a freaking good gaming magazine going on for 7 or 8 years around here in Bulgaria, which was, is, and will remain the best and most trustworthy source of information on games - Gamers' Workshop - but it has been discontinued
And yeah, some of the people behind it are still writing on the internet, but it doesn't count.
Other than that no, I don't trust reviewers. They tend to get over-boggled in their own perceived self-importance, and besides, it's hard to take Gamespot seriously when the highest rated games are CoD Black Ops, Civilization 5, Battlefield Vietnam and Cataclysm. Not to mention a tendency to give a 9 or 10 to every overhyped game that exists.
