But they talk stuff like Witcher 3 being the best detective game ever made. How is that even logical to think?
It's not. It's call an opinion. Nobody has, as yet, proposed a standard for determining the quality of a game in an objective fashion that has been independently peer-reviewed and accepted by the industry, and as such any claims that anything is the "best X" are going to be subjective.
Also from what I've heard, most of the research and information that they get are false
And I've heard jellybeans grow on trees. What "research and information" are you talking about and what is the basis for declaring that it is "false?"
It sounds like you're just here to stir up an argument, thus far, and that's not okay.
