The Backloggd Top 250 has a minimum requirement of 1000 ratings for a game to be eligible. This is a list of the 50 highest rated games that didn't meet that criteria. Consider it a list of true hidden gems.

Disclaimer:
When sorting by Average Rating, Backloggd seems to automatically discard every game with less than 300 ratings. As I can see no practical way to include the games below this threshold, I have decided not to. This means that there are probably a lot of high rated games that won't appear on this list until they get enough ratings, which somewhat defeats the purpose of the list, but what can you do.
