Theme Diversifiers are aimed at providing motivation for experienced game jammers. In a sense diversifiers are a voluntary list of secondary constraints, that the individuals and teams can choose to go for, or not, as they please. If they do go for one or more diversifiers, they get to check off those diversifiers as fulfilled when uploading their game.
