Too many douchebag reviewers score based on "tolerance for issues" and not on how fun the game is. That's how games like Deadly Premonition and Infinite Space rack up mediocre scores even though they're loved by actual gamers. Most reviewers are complete failures because they operate under the moronic assumption that somehow their opinions are so important that they can write a review that covers an entire audience. This is why any bland/boring Nintendo action/adventure game is guaranteed to get a 9+. Very little for pretentious reviewers to pick at, even if the game is yawn inducing. And it's also why reviewers in aggregate only identify a 1 point difference on a 10 point scale between Supreme Commander and SC2, even though any RTS fan can tell you that if SC1 is a 9, SC2 deserves a 4 at best. I'm sick of seeing games reviewed based on how polished they are and not on how fun they are.
Oh please Deadly Premonition deserves mediocre scores. There are a ton of things wrong with the game that have to effect the score. You can't score simply based on if you find a game fun. That is the mark of a terrible reviewer. A review and the score attached to it needs to reflect the ENTIRE game not just one or two elements of it.
