Most games that have been well marketed have lots of reviews, and thats awesome, they deserve it. But let's not forget about those games that did not get so lucky to get many reviews. There is a list in this website that shows the games with the least amount of ratings; and as voters, we should go check them out. I mean, who knows: maybe there's a perfect game that its not only fun and original but it fits the jam's theme perfectly with only 3 reviews.
Check the link to see those games with almost no ratings, bear in mind that some games have no ratings because they don't open/work properly. If that's the case, I think its safe to report those non-functional games
