And I should add, I don't think a 10/10 means a game is without flaws. I can forgive flaws. I see a 9+ game as a game that just comes together and completely shines in all aspects.
If The last of Us just had the wonky AI issues and bugs, I could see giving it an easy 9 but those clicker encounters really were just terrible. The clickers felt so random in when they hear you and moving that slowly only to die by randomness isn't fun.
