It depends on the game. I don't put much weight on review scores unless it's a game I'm on the fence about anyway.
To put it another way - I wouldn't buy a WWE game even if it got a 100 metacritic score. That's because the game doesn't interest me. But, if a new Halo FPS came out, I would buy it even if it was the worst reviewed game ever.
I was loosely thinking about buying Assassin's Creed Origins. But, I've tried one of the games before and lost interest. So, I was probably not going to buy it. Then I saw solid review scores, which prompted me to read reviews, which then prompted me to buy the game. If it had a 71 metacritic score, there is almost no chance I would have bothered to look further into the game, and ultimately I would not have purchased it.
