I feel as though the slavish adherence to it by some within gaming is different, though (and that a lot of the criticism, as anywhere, is seriously poor).
Personally, I never read music reviews. Ever. They are meaningless to me, in terms of guiding my behaviour or learning from them. Almost completely meaningless in that sense. Films a little less so, but still not much there either. I don't not value them in terms of their being expressions of criticism and such, but rather they don't mean much to me.
I suspect this is fairly widespread, although of course not universal, nor should it be. Yet games reviews seem different to me: the attention paid is different, dramatically, to how other criticism works. Music is so vast you can never read a review and revel in whatever and it's not the point and nobody will care. If you're considering a modernist composer's position, sure, then you get more serious and pay.more attention, but these are two different fields that happen to share 'music'. Gaming still feels cloistered and limited and narrow in this sense. Maybe anecdotal, maybe too 'hardcore' focused.
