My preferred approach is to ignore the number/percentage rating entirely, and focus on what the review actually says. Maybe the reviewer is marking it down because of stuff I don’t care about, and the good parts of the game are exactly the things I value highly. Or maybe they’ve given something a 9/10 but the things they love about it are things that would make me hate it. There are so many more important things when deciding if I want to buy and play a game than what overall percentage it was given in reviews.
