It is kinda expected that votes are going to be unfair unfortunately. There are so many games to vote, but only very few games will get more than 100 reviews.
In a perfect world everyone would have the exact same reviewing standard (and everyone would have time to play all games). In reality the standards and the interpretations of the votes will widely differ from person to person.
You can be unlucky and only get reviewers with high standards, while someone else is more lucky and only get reviewers with low standards.
Not sure if that's the case with these games though.
