Not necessarily, in theory someone who is bad at a game is still capable of grasping and understanding the finer points of the game mechanics, how they work, what decisions they can make, and extrapolate on higher level stuff.
That said it obviously is a benefit when you are good at a game and have a much better understanding of the game. A lot of reviews tho the problem isn't as simple as journos can be bad at games (which, lets be real), it's more so that they supremely suck at describing gameplay period. Most if not straight up all game reviews are written like movie reviews or are nothing more than describing what they felt like it was like to play the game.
There is very little detail given about the mechanics or explanation of decision making. There is every little understanding of higher level systems in a game, not one Bayonetta review has ever brought up Dodge Offset, which is absurd to anyone that understands that genre and that game. I get that sometimes this is a case of a game doing a poor job teaching you the game, but this is one example of many someone could make. Fighting game reviews for instance are the epitome of fucking terrible.
They've also often used poor language to describe shit and made a lot of it standard, when really it's never an acceptable take or even a justified take.
Criticism for art, our art as well should have a balance of being able to explain how the game works at a lower level play (when you're learning the game) and how it evolves at mid to high level play. And personally reviews don't satisfy any of that. And that necessarily doesn't need you to be good at video games, it requires more effort to learn the ins n outs of the game.
Honestly agree with this. I sometimes write reviews personally to share with my friends, and the one section I always spend the most time on is gameplay and seeing where things work and things don't, but on a broader level. I'm trying to finding the right balance between broad enough descriptions of gameplay and the nitty-gritty details.
