I also see many in the top 50 with less than 20 ratings. I thought we needed at least 20 to qualify?
This is what is confusing to me. It seems that 'winning' does not really mean anything (at least to my understanding). As you have rightly observed, there are games in top 50 with less than 20 ratings. By the rules, they haven't 'won' but they were given a ranking. So technically, a game with even 10 ratings of an average of 3.2 would outperform a game with 100 ratings with an average of 3.1 and get a better overall ranking :(
yup, this was my experience as well, i was fifth most rated in the jam with 201 ratings, and pretty consistantly in the top 10 for popularity, but ranked 206th in the overall.
I know that is a good result really, and hey, this was my first jam and my first attempt at making a game, but it still feels a little.. meh..
