This is actually something that can be debated too. How long does a person have to play a game to be "qualified" to review it. Also, how much experience does a reviewer have to have with a particular genre to be qualified to review the game?Letting another man decide what you gonna buy for yourself , especially when a lot of reviewers sound like they played 2 hours of a game/got paid to do a review by a game company, and/or describe any game as souls-like ( do people play other action rpgs?).
I think for the most part, I feel like a person should have to beat the main portion/campaign/story of a game to be able to review it, but I can also see that sometimes within X amount of hours it's possible to have a very good idea of the overall quality of a game.
I think reviews have gotten worse over the years though because of the rate we consume content now. Everything is a race to be the first to get a review out for clicks.
It takes how many years to create a game? And people are really assessing years worth of work in a few days, or even hours?
