81 is a low score...
BS opinions like this is why metacritic is worthless. One site will say a game has to be an 8 out 10 to just be "okay" while another will try to say 5/10 is average (probably to justify clickbait). Then all of these scores are pooled together for a distorted report on the actual quality of the game. Not to mention how gamers think anything under a 9 is utter crap these days (or make the claim at least).
If you ask me, scores are obsolete. Just give me a detailed review listing the pros and cons and if you recommend the game or not. That is all we need.
OT:
81 is a good score and the game will sell very well with no negative impact from said good score.
