This feature is now available in the HGnibus.
If you sort by ratings, you may notice that there are a number of games with a perfect 5.0 average rating, based on a very small number of reviews (less than five).
There are alternative approaches to “sort by rating” that incorporate the number of reviews, but we wanted the “sort by rating” feature to give players an opportunity to try unpopular games that are well-liked by those who play them. Over time, we hope and expect the games with a very small number of reviews will receive more reviews, and then their average rating will be more accurate.
Also note that many games have had a way to rate them for years, whereas others just gained the ability to rate them a couple of weeks ago. Just because a game has a small number of ratings doesn’t mean that it’s unpopular.
