I wish it had came from a better source that didn't all but sell out, but there's some slight truth in what they're saying regarding some places possibly scoring low just to be arbitrary, at least to me (Giant Bomb isn't one of them though. They're pretty legit and the shit they brought up regarding Fallout 4 was beyond true).
I read Edge for years and they were the main offender of this type of scoring to me, since some of their reviews felt like they were reaching to score low, especially if the review seemed to contradict the actual score. I'm sure it's not a popular opinion, but it's not like gaming journalism is immune from this type of stuff either.
It's funny because you reached this conclusion by doing the same thing you accuse Edge of doing. Starting with a narrative and working back. You have zero proof Edge or anyone else scores games lower "just for clicks" or attention, you are making this claim most likely because that they probably score a few games lower than you would have.
"Could it be that they felt differently than I do about a game, or that my interpretation of their review text doesn't match with the score they gave? No, no they must be doing it intentionally!"
