People wonder why Polygon's review matters...it matters because they're still considered a viable "opinion" by outsiders. Analysts & stock holders will see that and say, "Naughty Dog didn't completely hit this one out of the park". Also, with Polygon's shitty review system here are just a few games that had a better score than Last of Us.
Animal Crossing: New Leaf
Remember Me
Night of the Rabbit
Metro: Last Light
SimCity (2013) - original review
Gears of War Judgement
Dead Space 3
Black Ops 2
WWE '13
Some of those games are good, some bad, but I guarantee that none of them are as good as The Last of Us.
