With Edge giving it a 9 it's solely US Gamer's 2.5 holding it back from a 90. That one outlier is likely a (negative) million dollar review now. I should probably read it to see if it's well written/reasoned.
I find it kind of odd, but not completely unreasonably written. It's a pure opinion piece that ignored technical merits and relative implementation of mechanics though, hence why it ended up a low-average level score.
Really, looking through the authors other reviews and work, it just confuses me as to why they were given the game to review in the first place, because it makes perfect sense they'd have not had any fun with it given their apparent tastes.
But ultimately there is merit to it, even if it seem to have had a ridiculously pronounced effect on the average score most people will see despite being a massively divergent, singular outlier. I mean maybe the Author thought they'd love it from the trailers they'd seen, and was dipping their toes into waters they'd never trodden before, only to be disappointed to find it not to heir liking. That's a perfectly valid point of view, and for those that share the Authors tastes, an important warning for them to save their money.
