it's not really exaggerated to say that this tradition of reviewing games through scores is one of the biggest barricades that prevent it to ever become anything meaningful or even progress beyond MMM PERFECT GREAT 3D GRAPHICS 94 / 100. newest Disgaea somehow striking into the japfagger reviewer's soul (yesss pantyshots) thus it gets higher scores at Edge than what Deus Ex ever did..
Wait, movies get review scores too, as does music, and hell even sometimes books.
As for Deadly Premonition, a friend of mine bought it and I (and a bunch of others) watched him play it. It was pretty hilarious but it still didn't really look like something I wanted to play. Reading that review, it further looks like the kind of game that people say they like BECAUSE its bad. Which isn't my kind of thing.
Like watching movies so bad they're good. Which I also don't really enjoy doing. I generally just cringe while watching them and don't enjoy them.
I have a sneaking suspicion that people who say Deadly Premonition is awesome are just a vocal minority that have convinced themselves and each other that the mainstream reviewers don't know what their talking about.
Now, I don't think reviews are the end all way to determine if a game is worth playing but there is a general correlation between what I like (and how much I like it) and what the reviewers like. Obviously there are exceptions. Like I didn't enjoy Time Splitters 2 nearly as much as the reviews hinted I should like it (or other non-reviewers recommending it). And the couple of hours I played of Okami was good but not mind blowing like everyone says it was. On the other side of the spectrum though I haven't encountered any game that's gotten below a 35 on Metacritic that I can say after later playing it myself that it was a good game or that I really enjoyed it.
Actually, looking at Deadly Premonitions score. It got a 66. That isn't really that low. That is still "OK/Decent" range. Though I actually do generally trust IGN a lot they can be wrong sometimes. Anyway, I'm still not interested because 'quirky weirdness' is something I really don't care about, at least if that is all its got going for it and after reading a good chunk of that Something Awful review that seems to be really all it's got going for it.
Tangent: It seems a bit more rare that I agree with compiled user reviews because that score is effected by the loons that would visit the page, see that their favorite/most hated game has a score they disagree with and bomb it with a undeserved 0's or 10's. These stupid fanatics are what I like to avoid.
