You wanna know the greatest lie gamers ever told? That reviewers have to be good at games to review them.
The conversation should not be about good or bad.
But they have to be competent in order to understand the game well enough to explain it properly in their review.
I've read a bunch of reviews where the reviewer didn't even understand basic mechanics of the game.
In Tekken 4 for example, when you perform a normal throw, your character instead does a "push" in that particular game. (It's meant to be used near walls.) A reviewer who gave the game a 4/10 as I recall, was playing the game live on TV after his review was published, and repeatedly did the "push" move by accident, and kept saying "Oh, I did it again. I'm not sure how I'm doing that."
It's Square + X. Basic throw...
But yeah, go ahead and explain the game is like in a review with your vast knowledge of how to play it.
By the way, that initial jump in Cuphead was not the only problem with Takahashi's gameplay. His inability to make adaptations, and his sloth-like reactions for instance. But I'm not going to get into that.
