I watch ZP, but mostly for the giggles. But beyond that, I personally judge a game. I read the box, read articles, read Youtube comments to see, and watch a video myself. I think people who only get what a reviewer recommends really needs to learn a sense of free will.
Pretty much what I do to see if maybe I'll like a game or not.
Read a few articles, forums and youtube videos/comments(Not so much, but sometimes helpful)
