Unfortunately, Google Moderator doesn't let you rank search results by popularity. Moreover, it would be better if Google Moderator allowed you to vote on pairs of objects, with metadata attached to individual objects and also to object pairs. Another possibility is to write a Wikipedia article showing a "game design web", but that would probably go against wikipedia rules: most of the games would not be noteworthy and also there would probably be a lot of self-promotion by indie game developers.
