No, not at all.
Say you where a reviewer who was passionate about what they did, how much would a publisher have to pay you to inflate a review score? Bearing in mind that if you where found out, your career would be OVER. No publication would ever hire you again and (given how malicious gamers are when it comes to this sort of thing) your name would be dirt on social media where people would send you rape and death threats for the foreseeable future. You'd have to pa me a life's salary plus perks for me to even think about it.
Plus, publishers can't keep boxart a secret most of the time. How would a generation of paid off reviewers and the staff publishers employ to keep the money flowing to them ever stay quite? It would be the biggest story ever.
Crazy how people think there's a conspiracy of paid reviewers but seem to ignore the proven and infinitely more sinister tactics Publishers actually use to control the MC scores i.e blacklisting certain reviewers, bringing them to luxurious preview events and in the case of the last of us, placing a post embargo seal on 15 hours of gameplay so that reviewers are instantly limited to what can be discussed.
I know they are not being paid cash in hand, but they are being "paid" in exclusive hand shake deals. " tell everyone we did good, we give you follow up interviews, early press releases, jump in line preview press tours, early access etc. Worked in media for most of my years, there payment is in "kindness".
