So you can sort the submissions by either "Popular" or "Most rated". I'm not sure, but it looks like the most rated gives you games with most rating even if all of them are 1 star ones, and the poular one gives you the best rated games even with less ratings, but like, all 5 stars.
Like one of the Most Rated games is THE LEAST popular one. Which means it got a lot of bad ratings.
So how will the top 20 be formed in the end?
