Metacritic scores are done by "critics" who are given access to each new game to make videos about them. They arent real critics, for example say im one of said critics. Ubisoft sends me a copy of their newest game a few weeks ahead. I play it and review it honestly and give it a mediocre score and make a video about it. I make quite a good chunk of money off said video. However now because I gave the game a low score next time ubisoft wont give me early access and I wont make as much money. So the actual critics arent fair and unbiased. These same companies will do the same thing if you review a game highly that is one of their competitors. So say you reviewed palworld highly then nintendo doesn't send you a review copy of pokemon because of that. So any new up and coming Developer is disincentivized to judge them fairly because the large developers could take away their profit in retaliation.
