I trust them a lot. See, I know that just because I love a game doesn't mean it's a 100% game. While I'm able to form an opinion of my own, most reviewers give an accurate summary of the games quality. Megaman Zero 3 is one of my favorite games of all-time. However, I know the game has flaws, and it is not deserving of a 9.5 score. I would say the score it got—79% at gamerankings.com—is a very accurate score, despite my fondness for this game.
Something people should always remember: A game does not have to be a triple a game for you to love it. You don't have to like Mario Galaxy more than Megaman. You're free to like whatever it is you like.
