Polygon is a joke. They rated a $60 microtransacation cashgrab garbage a 7.5/10.
Review scores aren't relative to other review scores, and reviews are written by individuals, not institutions. One reviewer can appreciate a game more highly than a different reviewer appreciates a different game.
When I was working on a commercial RPG, we had a lot of positive, mixed, and negative reviews. Quite frankly, I liked the mixed reviews the best - because they were critical about a wider variety of issues and that feedback was useful to the team. Glowing positive reviews are nice to see, but whether they had any impact on sales was uncertain and there was no feedback we could use from them. Negative reviews tended to be single-issue opinions about things beyond our control, generally written in Russian, so there was very little we could take away from them to make our game better.
