I feel like this article perfectly shoots the idea of game critics in the foot, while also fully justifying standing its ground because the foot had a knife and was trespassing in the wrong shoe.
Here's the thing, if gaming scores are meaningless, because an opinion is too complex to display in a simple arbitrary 1-10 scale system, then that's fair enough. Even factoring in decimal points, that doesn't leave a lot of room for nuance between an 8.8 and a 9.0.
Having said that, if all game critics are giving their personal subjective opinion, then doesn't that kinda' make the whole idea of a critique...meaningless? I mean the opinion of the game is scene through a lens you, I, Susan Freeman from 4 miles away, Captain Ventris of the Ultramarines and Dracula can't replicate, ie the critic's themselves, assuming of course Uriel hasn't become another damned YouTube Lets-Player.
So then by what right does any critic at all dare to offer their opinion, if their opinion is applicable to themselves and nobody else?
Now to counter my own point, lets say we grant such Daring Do-ness to the critic by trusting them. Fair enough. I think Jim Sterling has a pretty good idea of what makes games good and bad. So I read his reviews and trust him. But then, if you trust them, then why shouldn't they give a numerical score? After all, the critique and score are scene through a lens we've chosen to trust.
So I'd say if we're willing to say 'Critic X's/Aggregate site's opinion of games is valid to me' I think we have to follow that up with 'And X's numerical score/aggregate score attempting to sum up their opinion, however weakly, is equally valid'. I don't think its possible to value an opinion or site while also devaluing a score.

R: either you trust the site/reviewer, or you don't. How they choose to publish their opinion is meaningless.
