Also, as for putting a score on a console...
It's a product review. If they want to attach a score, they can.
And while most outlets didn't attach scores to their reviews, Polygon are far from alone:
Yup, bitching about a site reviewing a console is hilarious. Tech sites review all kinds of hardware, and take into account the software lineup at launch (Windows phones always get a minus for the lack of apps). It might be a bit silly to give a score on such a review, but The Verge gives scores to all kinds of tablets and phones, so why not? I've got plenty of problems with Polygon, but them reviewing a console (when they've reviewed the Wii U and the Ouya, and will review the Xbone) should be the least controversial thing in the world.
