Ebert famously reviewed a few things without giving a score; I believe one of them was Human Centipede about which he said, to paraphrase, "You'll like this if this is the sort of thing you like."

There's a big aspect of genre siloing in gaming. Games tend to be developed very hard into specific genres and tropes, not all of which are things I like. However, game developers don't necessarily like to be categorized that way, so the way things are marketed can get very muddled. I like games that are the sort of thing that I like, and when creators are actively working against me finding out what kind of game they made, I don't always know what games are a good match for my tastes.

Then add to that: Often games will get very high ratings because the niche of players they cater to thinks the game is sitting near the apex of that niche--and nobody outside the niche is playing that game. But if that niche is, say, visual novels (which bore me to death), I'm not going to like a game. The high rating is, to me, a false signal.

But this is where curators can help! The fact that it's a specific person with that specific person's tastes is good if I happen to share those tastes. It helps me to avoid high-rated games that don't contain the elements I enjoy in a game; and to find the games that cater to my tastes but aren't marketed in a way that I recognize.
