Yes but buying a magazine is one thing, clicking on a link because you want to see how they justified a certain score is another. It only takes a second to click and scroll though a review.
You might not agree or rate that site afterwards as a review website, but it doesn't matter, they've still got your clicks, and they'll probably get them next time as well.
Clickbait works, and one website managing to get their review up a few hours early will generate a lot of clicks, regardless of whether they've played the whole game or not.
I don't even know what I'm arguing against actually. What was the question?
