I think the vast majority of game reviews use an inherently flawed system that will always lead to score inflation anyway.
Finding a good reviewer or reviewers who use a method you trust to consider the things you find important in a game is obviously going to give you a better result than hitting metacritic for the lowest common denominator value. If you're deeply into games using innovative systems, you're better off finding somewhere that gives a lot of weight to systems innovation in their final score than finding the average of the one place that reviews according to what interests you and 101 reviewers that will all automatically give a 90+ to every 'oh-please-god-not-another-fucking-FPS' that innovates technologically. Shinier graphics, same old derivative gameplay, 95/100! A new approach to the tired old trope of deformable terrain, NINETY EIGHT FOR YOU, lets not mention that you forgot to make it useful to blow holes in the wall. Again. Except for that one place. With the thing.
That said, games are the same as ever. A few treasures amidst piles of trash. I have to admit I have a list of about twenty games that I enjoyed from the nineties, compared to about... five or ten that I have enjoyed from the last ten years, but that says more about my preferences than the quality of games being produced.
