An extra misnomer on top of a simplified numerical value is a natural next move, really. It's not like this breaks any patterns we've come to know.
Aggregates have a useful and informative place. But people should be savvy enough to distinguish the roles of aggregate sites versus that of individual publication reviews. Gauging taste and quality comes down to a combination of both aggregates and individual publications you are privy to. There is a difference between calling a game great based on what's objective as opposed to a single subjective, open-ended, relatable opinion. Nothing wrong with the former, per se -- but sometimes it's forgotten that turning it into an absolute byline is an option, not mandatory. Particularly when marking it down to the very digit.
It is probably safest to say that all games with a score of 3 or lower are at least pretty bad, or, similarly, all games with a score of 96 or above are at least okay. It is less so to say that only games scored 90 or above are the best games of their respective year, or every game below 80 is a waste of time. A game beloved by most of the review circuit is not necessarily absolutely equivalent to modern classics, but it's probably a well-made work. It's the small disparities -- not big ones, but subtle distinctions that can pinpoint the characteristics of a game's surrounding discourse.
Another form this manifests in is in the different demographics of art/entertainemnt. Most media can be spliced in three portions. As applied to this hobby, it can be spelled out like so:
A game that is loved by the critics and loved by the gamers may not be loved by yourself. You may also love a game that the critics enjoy but the mass gaming 'consumer'-base has a distaste for, while another day, the critics may pile on something that both you and the wider gamer base adore. And etc.
It's important to remember what correlates with what, and where the values held by the game press community fall with respect to yours, as well as the general, current state of video game critique and its relationship with both you and the gaming community.
As for the badge, it's just putting into graphic what many people already stand by to some extent, anyway. It's the branch, not the tree.
